In this paper, the electrical characteristics and sensitivity analysis of staggered type p-channel heterojunction electron-hole bilayer tunnel field effect transistor (HJ-EHBTFET) are thoroughly investigated via simulation study. The minimum lattice mismatch between InAs/GaAs0.1Sb0.9 layers besides low carrier effective mass of materials provides high probability ...

We study the non-equilibrium dynamics of small, strongly correlated clusters, described by a Hubbard Hamiltonian, by propagating in time the Kadanoff-Baym equations within the HartreeFock, 2 Born, GW and T-matrix approximations. We compare the results to exact numerical solutions. We find that the T-matrix is overall superior to the other approximations, and is in good agreement with the exact ...

A spatially non-dissipative, implicit numerical method to simulate turbulent reacting flows over a range of Mach numbers, is described. The compressible Navier–Stokes equations are rescaled so that the zero Mach number equations are discretely recovered in the limit of zero Mach number. The dependent variables are co-located in space, and thermodynamic variables are staggered from velocity in t...

An implicit function is defined to be the zero set of a scalar function F over space. Further, for points not on the implicit function, the sign of this scalar function tells us whether the point lies inside or outside the implicit function. The choice of whether positive values are inside or outside is arbitrary, since we may multiply an implicit function by −1 and change the notion of inside ...

In this work we construct a multiderivative implicit-explicit (IMEX) scheme for class of stiff ordinary differential equations (ODEs). Our solver is high-order accurate and has an asymptotic preserving (AP) property large singularly perturbed ODEs. context, the AP means that singular limit discretely preserved when parameter ? goes to zero. The proposed method based upon two-derivative backward...

We study the nonequilibrium dynamics of small, strongly correlated clusters, described by a Hubbard Hamiltonian, by propagating in time the Kadanoff-Baym equations within the Hartree-Fock, second Born, GW, and T-matrix approximations. We compare the results to exact numerical solutions. We find that the time-dependent T matrix is overall superior to the other approximations, and is in good agre...
