Rapid Performance Optimization Method for Photoelectrodes

Sophia Haussener, Yannick Kenneth Gaudy

We report the development of a rapid method for the performance optimization of photoelectrodes. The method requires as an input incident photon-to-current efficiency (IPCE) measurements of a material at two or more wavelengths, an estimation of the comple ...

Low-temperature growth of n(++)-GaN by metalorganic chemical vapor deposition to achieve low-resistivity tunnel junctions on blue light emitting diodes

Nicolas Grandjean, Jean-François Carlin, Pirouz Sohi, Yao Chen, Mauro Mosca

We report on low-resistivity GaN tunnel junctions (TJ) on blue light-emitting diodes (LEDs). Si-doped n(++)-GaN layers are grown by metalorganic chemical vapor deposition directly on LED epiwafers. Low growth temperature (

InAlN underlaver for near ultraviolet InGaN based light emitting diodes

Nicolas Grandjean, Jean-François Carlin, Mauro Mosca, Camille Haller, Rolf Erni

We report on InAlN underlayer (UL) to improve the efficiency of near ultraviolet (NUV) light emitting diodes (LEDs). While InGaN UL is commonly used in high-efficiency blue LEDs it may absorb light for shorter wavelengths. InAlN lattice-matched to GaN exhi ...
