Abstract(in English) | We report a Monte Carlo analysis of base transit time in ultra-thin and heavily-doped InP/InGaAs HBT's. In ultra-thin base layer less than 20nm, the influence of the plasmon scattering in electron transport is significant. Therefore, it is effective to use graded base in order to sweep out quasi-thermalized electrons. As for graded base, we carried out Monte Carlo Simulation under the condition that the total of graded energy and conduction band discontinuity between base and emitter is constant. Although the best graded energy to minimize base transit time is from 5kT to 7kT, small grading such as 1-2kT is also effective. When 2kT grading is introduced in 20nm base, 40% reduction of base transit time is calculated. |
