Fabrication and Characterization of AlGaAs/GaAs HBT
AlGaAs/GaAs HBT의 제작과 특성연구
Abstract
We have fabricated n-p-n HBTs using 3-inchAlgaAs/GaAs hetero structure epi-wafers grown by MBE. DC and AC characteristics of HBT devices were measured and analyzed. For HBT epi-structure, Al composition of emitter was graded in the region between emitter cap and emitter. And base layer was designed with concentration of 1
