报告一 (15:00-16:00)Plasma: enabling materials and energy conversion

Absract: Plasma, the fourth state of matter, is a partially or fully ionized gas. It has exceptional properties because its composition, density and temperature can be varied over enormous ranges. In this talk I will discuss the use of plasma in materials processing and energy conversion, such as plasma etching, plasma enhanced material deposition & modification, plasma activated extreme ultraviolet (EUV) lithography, plasma  driven carbon dioxide conversion and so on.

报告二 (16:00-17:00)Twisted 2-D materials

Absract: Van der Waals (vdW) heterostructures, in which a wide range of unique atomic layers can easily be combined, offer novel prospects to engineer and manipulate quantum confined states. Here I will present two approaches to this exciting prospect. I will first present Coulomb blockade in a vdW quantum dot device with tunnel coupling to a tunable Fermionic reservoir. Hybrid excitons, composed of localized quantum dot states (in WSe2) and Fermi reservoir continuum states (in graphene), are observed due to ultra-strong spin-conserving tunnel coupling resulting from an atomically thin tunnel barrier (hBN). Secondly, I will present evidence for quantum confined states engineered by the periodic potential landscape of interlayer valley excitons in a vdW heterostructure. Here, the moiré potential of a twisted MoSe2/WSe2 heterobilayer traps interlayer excitons. We show that the trapped interlayer excitons inherit the magneto-optical properties of the type-II band-structure, opening new ways to engineer quantum confined states in vdW heterostructures.

报告三 (17:00-18:00)Optoelectronic Research at the University of Essex

Absract: In this presentation I will outline the research undertaken in my laboratories, covering the design, fabrication, and testing of new material photodetectors, the fundamental study of dilute Bismide semiconductors, and the design, and building of a new concept THz spectrometer. The technical presentation will be proceeded by a short introduction to the University of Essex. The technical presentation will be followed by some discussion on possible research areas for future collaboration between Essex and  CQUPT.
