MOVPE growth and characterization of Cr-doped GaN
… the first time with the intention of producing a dilute magnetic semiconductor (DMS) with room temperature ferromagnetism. To this end the following growth parameters were investigated and optimized: carrier gas, precursor access and ratios, and growth temperature as well as post growth annealing. …

Character of the electronic states near the metal-insulator transition in Gallium Manganese Arsenide
… metal-insulator transition in the ferromagnetic semiconductor Ga1-xMnxAs is studied by cross sectional scanning tunneling microscopy. 200nm thick samples grown by MBE at UCSB with doping levels from 1.5%, close the metal-insulator transition, to 5%, deep into the metallic regime, were …
