Oxide Heterostructures

We investigated the structural stability and electronic properties of WS2 and graphene oxide (GO) heterostructures via first-principles calculations. It is found that the band gap and the work function of the WS2/GO heterostructures can be efficiently tuned by changing the oxygen functionals and its concentrations.

Structure Properties

First-principles pseudopotential calculations have been performed to investigate the structural stability and electronic properties of magnesium considering three possible structures under high pressure. The results show that magnesium crystallizes in the hcp structure is to be the most stable structure at the ground state, because of the lowest total energy. Magnesium undergoes a pressure-induced phase transition from the hcp structure to bcc structure at 65 GPa. And no further transition is found up to 220 GPa. The electronic structure properties of three structures of magnesium are also calculated and discussed. The structural stability mechanism is also explained through the electronic structures of three phases.
