First principle study of Germanium and Selenium doped monolayer black phosphorus

Tejaswi Issarapu C.S., Junghare R.C., Patil G.C., Visvesvaraya National Institute of Technology Nagpur, IN

Within the framework of density functional theory, we investigate the effects of dopants germanium and selenium on the electronic properties of monolayer black phosphorus. Dopants are introduced in two possible chemisorption and substitution configuration. Findings [...]

Characterization of electrical property and band-structure in carbon nanotube/GaN hetero-interface

Yokogawa T., Miyake S., Yamashita A., Yamaguchi University, JP

Recently power devices using GaN have attracted much attention because of high power and high efficiency due to the wide band-gap. These power devices are generally used in high temperature operation by the heat dissipation [...]

ALTRAS-CNFET: Full-Band Based Quantum Transport Simulator for Carbon Nanotube Field Effect Transistor Engineering: From Chirality to Device Performance

Tao Y., Liu F., Bian W., Man T.Y., Chan M., He J., Shenzhen Graduate School, Peking University, CN

ALTRAS-CNTS is a powerful full-band based quantum transport simulator for CNT energy-band and CNFET performance calculation. It can directly compute device tunneling gate current in the radial direction, drain current in the channel and other [...]

Capacitance-Voltage Characteristics of Metal-Oxide-Strained Semiconductor Si/SiGe Heterostructures

Cavassilas N., Autran J-L, CNRS, FR

We present theoretical investigation of mechanical strain-induced effects in metal-oxide-semiconductor (MOS) structures from an electrical point-of-view. In this work, we start by calculating the strained semiconductor band-structure using a k.p approach over the complete Brillouin [...]

Phase Stability and Thermoelectric Properties of Alkali-Metal Doped Group IV Clathrate Compounds

Rousseau R., Toderov E., Uehara K., Tse J.S., National Research Council of Canada, CA

The relationship between phase stability and structure of alkali metal doped clathrate compounds of C, Si and Ge is investigated by a combination of first principles band structure calculations and qualitative tight binding theory. The [...]
