In this paper, the hybrid implicit-explicit finite-difference time-domain (HIE-FDTD) method is proposed for efficient simulation of graphene-based frequency selective surfaces (GFSS) at Terahertz band, with the Drude model of monolayer graphene and associated auxiliary differential equation (ADE) technique implemented into the numerical methods for solving the Maxwell's equations. Numerical simulations...
In this paper, solid phase epitaxy (SPE) process is proposed to improve phosphorous activation and hence reduce the contact resistivity of n+/p junction for Ge n-MOS technology. Over 1×1020 cm−3 electrical concentration and about 1.75×10−6 ohm·cm2 contact resistivity have been achieved at P+ implantation of 10keV and 5×1014cm−2 and annealing condition of 600oC, 10seconds. The fabricated N+/P diode...
In this letter, the specific contact resistivity of metal on n-doped germanium is significantly reduced to by multiple implantation and multiple annealing (MIMA) technique. The dramatic reduction of specific contact resistivity is attributed to the enhanced activation of n-type dopants, and a high electrical activation over ...
A new calorimeter for measuring the thermal conductivity of liquids has been constructed. It is a totally automatic instrument utilizing computer control. The time of measurement is 1 s and the temperature rise due to heating is within 1°C. The instrument has been calibrated at 25°C using six reference liquids. The accuracy is better than 1% and the precision is about 0.2%. The thermal conductivities...
