German-US team make graphene-like material

German-US team make graphene-like material

By BizLED Bureau July 10, 2015: A team of Chemists at the Technical University of Munich (TUM) replaced individual phosphorus atoms with arsenic to develop a 2D semiconducting material. In collaboration with the Munich chemists, American chemists have built the first field-effect transistors with the help of the new material. Graphene consists of one single layer of carbon atoms, similar ...

Photonic crystal enhances light output of GaN-based flip-chip LED

Photonic crystal enhances light output of GaN-based flip-chip LED

By BizLED Bureau July 3, 2015: A team of researchers at the Chinese Academy of Sciences? Institute of Semiconductors could successfully enhance light output from GaN-based flip-chip LEDs by 42%. This breakthrough was possible by embedding a photonic crystal (PHC) structure at the juncture between the p-GaN and silver reflector. The light output capability of LEDs with the integrated photonic ...
