Growth of AlGaN under the conditions of significant gallium evaporation: Phase separation and enhanced lateral growth
The growth kinetics of AlGaN in NH3 MBE under significant Ga desorption was studied. It was found that the addition of gallium stimulates 2D growth and provides better morphology of films compared toExpand

Sgoldstino events in top decays at the LHC
Abstract We study top-quark decays in models with light sgoldstinos. The off-diagonal entries in the squark mass matrices can lead to FCNC top two-body decays into a sgoldstino and a c (or u) quark.Expand
