Abstract
We found that the relaxation rate of strained InAs during growth interruption in the molecular beam epitaxy (MBE) chamber depends strongly on InAs layer thickness and As4 background pressure. By reducing the As4 background pressure, we successfully prevented lattice relaxation of a 6 nm InAs layer, which is 1.5 times thicker than previously reported critical thickness on an InP substrate
