A charged finding—effect of threading dislocation lines on conductivity in gallium nitride versus indium nitride

By Lisa McDonald / May 26, 2023

Group-III-nitride semiconductors have considerable potential for electronic and optoelectronic applications, but unintended defects tend to form in their structure during fabrication, which may affect the electrical properties. Two researchers at the University of British Columbia detailed the striking contrast between the effects of threading dislocation lines in gallium nitride versus indium nitride.
