Polariton physics in novel 2D materials

在这个项目中，学生将探索原子薄的二维半导体过渡金属二硫族化合物（TMDs）中的强光-物质相互作用。主要目标是：(1)制造包含门控异质结构的tmd微腔器件，使激子复合物的电场控制成为可能；(2)基于三角子和间接激子的稳健门控TMD极化观测。如果在合理的时间尺度内达到这两个目标，那么学生将学习极化态中的非线性现象。

In this project the student will explore the strong light-matter interactions in atomically thin two-dimensional semiconducting transition-metal dichalcogenides (TMDs). The principal objectives are (1) Fabrication of TMD-microcavity devices comprising gated heterostructures enabling electric field control of exciton complexes; (2) Observation of robust gate-controllable TMD polaritons based on trions and indirect excitons. If the two goals are reached on a reasonable time-scale, the student will then study non-linear phenomena in the polariton regime.
