RESEARCH INTERESTS
Our current research focuses on rational design and synthesis of functional semiconducting nanomaterials and heterostructures,
systematic investigations on their physical properties and exploring their potential applications in nanoelectronics and
nanophotonics such as field-effect transistor, photodetectors and light-emitting devices.

Rational design and synthesis of mono-and few-layer two-dimensional transition metal dichalcogenide microplates and their
heterostructures; fabrication the vertical stacking structures based on the as-synthesized microplates or exfoliated microplates
by using aligned and transferred method.

Investigations on their fundamental properties such as carrier transport among layers and how depletion electric-field, defects
and impurities, confined geometry and anisotropy alter their optical and electronic properties by using optical spectroscopy and
electrical transport measurement.

Exploring the applications of these heterostructures in nanoelectronics and nanophotonics, especially in ultrathin flexible
light-emitting devices and circular-polarized light-emitting devices.

Studies on how external electric-field affect the phase transition process in the organolead halide perovskite crystals and
exploring their applications in the electric-field-modulation dual color photodetection and light-emitting devices.
