Multi-band simulation of interband tunneling devices reflecting realistic band structure
2000 International Conference on Simulation Semiconductor Processes and Devices (Cat. No.00TH8502), 2002We have studied quantum transport in a Si interband tunneling diode (ITD) based upon a tight-binding nonequilibrium Green's function method. In the simulation, an empirical tight-binding theory has been used to take into account realistic band structures. Comparison has been made between the results of our multiband (MB) model and those of conventional

Wigner-function approach to multi-band transport insemiconductor devices
2002We review and compare three different models for the description of multi-band transport of charge carriers in semiconductors. They are based, respectively, 1) on the Floquet decomposition of the state space, 2) on the Wannier-Slater definition of envelope functions, 3) on the Kane model.

Multi-Band Model Hamiltonian for Tunnel Devices with Van Der Waals Heterojunctions
2025 International Conference on Simulation of Semiconductor Processes and Devices (SISPAD)We study the electronic properties of a van der Waals (vdW) heterostructure made of SnSe2 and WSe2 by abinitio methods in order to simulate an Esaki diode built with these materials. We use Density Functional Theory (DFT) to parametrize a k · p model in order to achieve the transport calculations.

The Linear Array Multi-Band Selection Device Role In Remote-Sensing Instrument Design
SPIE Proceedings, 1984This paper presents a figure-of-merit parameter for the scientific utility of multi-spectral linear array (MLA) instruments for civil remote sensing. The utility parameter is based on the observation that most analyses of earth resource satellite data are based on algorithms which combine measurements from two different spectral bands. Thus, the number
