[Pw_forum] Surface Passivation in slabs of III-V material using pseudo hydrogen

2015-08-24 Thread Piyush Kumar
Dear all, I am trying to calculate the bandstructure of InAs slab using QE-5.1.1. But, I am getting lots of surface states. I tried hydrogen passivation, but it did not work. In one paper [1], it has been mentioned that to passivate the surface dangling bonds in III-V materials, we need to use pse
