Conductive atomic force microscopy ~C-AFM! and surface photovoltage ~SPV! microscopy were used to investigate local electronic structure in p-type GaN. C-AFM imaging revealed locally reduced forwardand reverse-bias conductivity near threading dislocations. In addition, regions near threading dislocations demonstrated significantly enhanced surface… CONTINUE READING
