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.

To date, efforts to study carrier dynamics in semiconductor materials have primarily focused on narrow bandgap semiconductors. Researchers at the University of California, Berkeley, propose a method that combines ultrafast nanoscale measurements and theoretical modeling to probe carrier behavior in semiconductors with wider bandgaps.

Awareness of lead’s toxicity drives research on alternative lead-free piezoelectric materials. But traditional high-temperature sintering processes can inadvertently deteriorate a lead-free ceramic’s piezoelectric response. A two-step sintering process can minimize this deterioration, and researchers in China identified the optimum temperature and dwell time for the first step.

In recent years, conflicts over spectrum usage by private, public, and federal entities have reached a fever pitch. The Federal Communications Commission and the National Telecommunications and Information Administration, as well as House and Senate committees, are considering initiatives and legislation to reform and improve spectrum management.
