The growth of nonstoichiometric GaAs shells is achieved through the formation of As antisite defects, and to a lower extent, after annealing, As precipitates. Because of the high density of atomic steps on the nanowire sidewalls, the Fermi level is pinned midgap, causing the ionization of the subsurface antisites and the formation of depleted regions around the As precipitates. Controlling their incorporation offers a way to obtain unique electronic and optical properties that depart from the ones found in conventional GaAs nanowires.}, cin = {PGI-5}, ddc = {540}, cid = {I:(DE-Juel1)PGI-5-20110106}, pnm = {141 - Controlling Electron Charge-Based Phenomena (POF3-141)}, pid = {G:(DE-HGF)POF3-141}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000363003100023}, doi = {10.1021/acs.nanolett.5b01802}, url = {https://juser.fz-juelich.de/record/255938}, }
