Department Colloquium: Prof. Lukas Novotny, (ETH Zürich, Schweiz) talks about:
Low-Dimensional Optoelectronics
Abstract
To co-integrate photonics with electronics the length-scale of optical devices has to be reduced below the wavelength of light. To achieve this goal we interface optical antennas made of noble metals with low-dimensional materials, such as graphene, hexagonal boron- nitride (hBN) and transition-metal dichalcogenides (TMDs). Optical antennas enhance the interaction strength and boost the efficiency of low-dimensional optoelectronic devices. In this talk I will describe our progress in the fabrication and characterization of light- emitting devices based on inelastic electron tunneling. I will show that the emission can be enhanced by non-radiative energy from tunneling electrons to TMD excitons.
The Colloquium will be held in "hybrid" format, i.e., you can join the talk in the lecture hall or via zoom.
