External control of GaN band bending using phosphonate self-assembled monolayers
T. Auzelle, F. Ullrich, S. Hietzschold +7
We report on the optoelectronic properties of GaN and surfaces after their functionalization with phosphonic acid derivatives. To analyze the possible correl…

Kinetic modelling of carrier cooling in lead halide perovskite materials
Thomas R. Hopper, Ahhyun Jeong, Andrei Gorodetsky +6
The relaxation of high-energy "hot" carriers in semiconductors is known to involve the redistribution of energy between (i) hot and cold carriers and (ii) hot carriers and phonons.…

Electronic properties of air-exposed GaN and surfaces after several device processing compatible cleaning steps
Thomas Auzelle, Florian Ullrich, Sebastian Hietzschold +6
We report on the electronic properties of GaN and surfaces after three different and subsequent device processing compatible cleaning steps: HCl etching, ann…
