Exploration of a new reconstructed structure on GaN(0001) surface by Bayesian optimization

Akira Kusaba, Yoshihiro Kangawa, Tetsuji Kuboyama +1

GaN(0001) surfaces with Ga- and H-adsorbates are fundamental stages for epitaxial growth of semiconductor thin films. We explore stable surface structures with nanometer scale by t…
