On the trail of causes of radiation events during space flight

Scientists have made significant progress in understanding the sources of radiation events that could impact human space-flight operations. Relativistic electron precipitation (REP) events are instances when high energy electrons ...

A new all-2-D light-emitting field-effect transistor

Transition metal dichalcogenides (TMDs), a two-dimensional (2-D) semiconductor, are promising materials for next-generation optoelectronic devices. They can emit strong light due to the large binding energies of excitons, ...
