UVC LEDs on Bulk AlN Substrates Using Silicon Nanomembranes for Efficient Hole Injection
Sang June Cho, Dong Liu, Jung-Hun Seo +12
As UV LEDs are explored at shorter wavelengths (< 280 nm) into the UVC spectral range, the crystalline quality of epitaxial AlGaN films with high Al compositions and inefficient ho…
