Dispersion Interactions in Calculations of Properties of Energetic Materials

Wojciech Cencek; Fazle Rob; Krzysztof Szalewicz; Rafal Podeszwa; Betsy M. Rice; DeCarlos Taylor 2010 DoD High Performance Computing Modernization Program Users Group Conference, 2010

Until recently, first-principles calculations of potential energy surfaces (PES) were restricted to intermolecular interactions involving molecules containing just several atoms. This was due on one hand to high costs of wave- function-based electronic structure methods and, on the other hand, to the failure of the density functional theory (DFT) approaches to reproduce the dispersion part of intermolecular interactions. One solution ...

  • The Fundamental Laws of Electromagnetism

    In this chapter, the author offers a concise presentation of all the basic laws of electromagnetism¿¿-¿¿that is, the laws of Gauss, Amp¿¿re (with Maxwell's added displacement current), and Faraday, as well as Gauss's law for magnetism and the definitions of E and B by means of induced forces. This way the authors provide some basic knowledge to those who have not previously encountered them. Forces, currents, potentials, and fields used in the chapter can all be time-varying. The chapter starts with the definitions of electric and magnetic fields, which link the worlds of mechanical and electromagnetic phenomena. The chapter concludes with the short biography of Faraday, Gauss, Maxwell, Amp¿¿re and Lorentz.

  • Bulk MOSFET

    This chapter focuses on the DC characteristics of bulk metal oxide semiconductor field¿¿¿effect transistor (MOSFET), and presents a theoretical analysis of the subthreshold and post¿¿¿threshold current characteristics as an aid to low¿¿¿energy device design. In a short¿¿¿channel bulk MOSFET, drain¿¿¿induced barrier lowering (DIBL) near the source junction at the front interface significantly degrades the subthreshold swing (SS). Band¿¿¿to¿¿¿band tunneling often occurs in the gate¿¿¿drain overlap region. It is sometimes called the gate¿¿¿induced drain leakage (GIDL) current. For MOSFETs with a thin gate oxide, it has a significant influence on DC and AC operation. In the bulk MOSFET, the thermal conductivity of the substrate is not so high. According to simulations, the temperature near the drain junction quickly rises to 100¿¿¿¿¿C. Since self¿¿¿heating effects degrade the surface mobility of carriers, they must be taken into account. In electrostatic¿¿¿discharge (ESD) protection circuits, self¿¿¿heating effects reduce the temperature margin for the second breakdown.

  • Capacitance Computations

    This chapter considers capacitance modelling and capacitance concept for multiconductor geometries. Capacitance computations also represent a key component of partial element equivalent circuit (PEEC) models. Two interesting approaches namely integral equation (IE) methods and differential equation (DE) Methods are used for capacitance computations are presented. We also can combine some models based on DE techniques together with partial PEEC model inductances. For this reason, the chapter also considers simple DE circuit¿¿¿based models. Graphical techniques were used to approximate such solutions in the precomputer era. The chapter considers important issues regarding the influence of the mesh subdivision on the solution accuracy. It is clear that the accuracy of the computed capacitance values depend on the quality of the mesh. The concept of multiconductor capacitance is important for many different aspects of modeling of real situations. Most of the techniques apply to two¿¿¿dimensional as well as three¿¿¿dimensional geometries.

  • SOI MOSFET

    The partially depleted (PD) n¿¿¿channel silicon¿¿¿on¿¿¿insulator metal oxide semiconductor field¿¿¿effect transistor (SOI MOSFET) has a quasineutral region in the silicon¿¿¿on¿¿¿insulator (SOI) layer. This configuration is very similar to that of the bulk metal oxide semiconductor field¿¿¿effect transistor (MOSFET) except for the buried oxide layer beneath the device region. Therefore, most operation characteristics are similar to those of the bulk MOSFET. It is well known that a simple fin field¿¿¿effect transistor (FinFET) shows the characteristics of the double¿¿¿gate MOSFET or the triple¿¿¿gate metal oxide semiconductor field¿¿¿effect transistor (TG MOSFET), depending on device geometry and device parameters. This chapter explores how the FinFET structure changes drivability with the aid of three¿¿¿dimensional (3D) device simulations. It compares the simulation results of planar double¿¿¿gate silicon¿¿¿on¿¿¿insulator metal oxide semiconductor field¿¿¿effect transistors (p¿¿¿DG SOI MOSFETs) to those of SOI FinFETs that work as triple¿¿¿gate FETs.

  • Electromagnetic Theory: Basic Review

    This chapter brings together fundamental electromagnetic (EM) concepts, mathematical relations, and physical meanings. It illustrates three well-known coordinate systems and discusses the relations among them. Electromagnetic problems such as antenna radiation or radar crosssection prediction are better modeled via vector (and scalar) potentials. The concept of delta function is used in EM source representations. Guided wave propagation problems in telecommunications media are best treated using reduced equations obtained from the longitudinal and transverse decomposition of Maxwell equations. This yields the well-known transverse electric (TE), transverse magnetic (TM), and transverse EM (TEM) field representations under different polarizations. Electromagnetic problems involve linear, second-order differential equations. Any linear, second-order PDE can be classified as elliptic, hyperbolic, or parabolic.

  • Si Resonant Tunneling MOS Transistor

    The physical limit of the channel length for conventional MOSFETs is a quantum mechanical length: the direct tunneling (DT) of electrons from the source to the drain occurs via the band gap without applying a voltage to the gate. State¿¿¿of¿¿¿the¿¿¿art transistors with variety of operation principles have been proposed to improve conventional MOSFETs. The Si resonant tunneling MOS transistor (SRTMOST) is one of the potential candidates for a next¿¿¿generation transistor. In this chapter, the configuration of SRTMOST is introduced. Asymmetry of the double barriers and transistor operation in the subthreshold region are crucial for the high performance of SRTMOST. The transconductance gm and subthreshold swing, SS values, which are given by the analytical method, and an application to the logic circuit of the SRTMOST will then be discussed.

  • Personal Protection (Safety)

    The main issues regarding electrical safety are the invisible nature of hazardous situations and the element of surprise. One has to anticipate, visualize, and plan ahead for the unexpected and follow all the proper safety rules before an accident to gain confidence in working around electricity. There are several methodologies and personal protective equipment (PPE) available that make working conditions around electrical equipment safe. This chapter explains the common methodologies and safety equipment. There are two aspects of electrical safety; electric shock or current flow through the body and arc¿¿¿flash or being burned by the heat created by an electrical arc when equipment failure occurs. Construction and maintenance crews work on power lines under¿¿¿energized and deenergized conditions. Electrical arc¿¿¿flash hazards are serious risks to worker safety. In most applications, clothing and PPE must be either flame resistant (FR) rated or arc¿¿¿flash rated. Home safety also involves the awareness of touch and step potentials, arc¿¿¿flash too.
