Researchers can optimize the performance of multi-layered, post-fabricated organic photovoltaic devices doped with gold nanoparticles by using combined X-ray diffraction and X-ray fluorescence.

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team led by Professor Sungjae Cho in the KAIST Department of Physics developed a thickness-controlled black phosphorous tunnel field-effect transistor (TFET) that shows 10-times lower switching power consumption as well as 10,000-times lower standby power consumption than conventional complementary metal-oxide-semiconductor (CMOS) transistors.
