Research Interests:
My research involves model study and first-principles calculations of structural and electronic properties of two-dimensional materials. My previous study focuses on the nucleation and growth behavior of two-dimensional atomic crystals on different substrates, such as the most stable configurations of initial clusters, the formation energy evolution of clusters, the nucleation rate, nucleation barrier and so on. To prepare two-dimensional atomic crystals with high quality and yield, another interested point is the study of experimental conditions on the growth behavior, such as temperature, source pressure and substrates. I also devote myself to study the electronic properties of two-dimensional materials and their variation after stacking to vertical heterojunctions, which are useful in electronic devices. My recent study is the effect of impurity atoms on the electronic property at interface of two-dimensional lateral heterojunctions.
