Abstract: Tuning the desorption temperature of an As cap layer allows to achieve In0.53Ga0.47As(001) surfaces with (2 x 4) and (4 x 2) reconstructions which exhibit different chemical reactivity upon exposure in atmospheric pressure. Trimethyl-Al based atomic layer deposition of Al2O3 films on the two exposed surfaces causes a non-equivalent interface composition. This behavior is associated with a worse electrical quality of the interface with the exposed (4 x 2) In0.53Ga0.47As reconstruction. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3659688]
