Muhammad Usman, a pioneer of GaN-based light-emitting diodes and laser diodes in Pakistan, believes microLEDs will continue to attract interest in the research community.
"Similarly, LEDs and LDs in the ultraviolet spectrum have recently picked up due to their disinfection capabilities," he said.
Usman’s interest extends beyond pure research to the real-world effects of LED technologies and he is the co-author of a study on the potential energy and cost savings (128 TWh and $10.8 billion) from replacing traditional lights with LEDs in Pakistan, India and Bangladesh.
"Without any technological infrastructure for the design, fabrication, and characterization of III-V-based materials and devices, it has been a mounting challenge to pursue this research interest," said Usman, who states his career has been helped by his family and Pakistan’s Higher Education Commission, which awarded him a PhD Scholarship under the supervision of Professor Jong-In Shim, who introduced and trained him in III-V light-emitting diodes.
