Growth and characterization of carbon doped GaAs- and InP- based heterojunction bipolar transistors

The results described in this work demonstrate the comprehensive characterization of C-doped GaAs and In0.53Ga0.47As materials and C-doped GaAs-based and InP-based HBT devices grown by SSMBE system using CBr4 as p-type dopant precursor. The characteristics of C-doped GaAs materials, such as the hole concentration, mobility, lattice mismatch, surface morphology, and optical properties, have been comprehensively investigated using various techniques, which help to gain me insight and understanding of the material properties.DOCTOR OF PHILOSOPHY (EEE
