Single-mode lasing in whispering-gallery mode (WGM) microresonators is challenging to achieve.In bottle microresonators,the highly non-degenerated WGMs are spat
In this work,we demonstrate that ultraviolet (UV) laser photolysis of hydrocarbon species alters the flame chemistry such that it promotes the diamond growth ra
Cross-gap light emission is reported in n-type unipolar GaN/AlN double-barrier heterostructure diodes at room temperature.Three different designs were grown on
