III-V antiphase boundaries are not generated by Si or Ge substrate step edges

Charles Cornet, Sreejith Pallikkara Chandrasekharan, Audrey Gilbert +7

We critically review recent experimental and theoretical advances on the valence- and structure-mismatched heteroepitaxy of III-V semiconductors on group-IV substrates. We examine…

Inevitable Si surface passivation prior to III-V/Si epitaxy: A strong impact on wetting properties

S. Pallikkara Chandrasekharan, D. Gupta, C. Cornet +1

Here, we quantitatively estimate the impact of the inevitable Si surface passivation prior to III-V/Si hetero-epitaxy on the surface energy of the Si initial substrate, and explore…
