Nanophotonics for Optoelectronic Applications in Emerging Material Platforms

Abstract: 

Light–matter interactions underpin a wide range of technological applications, including photovoltaics, photodetectors, lasers, etc. At the most fundamental level, these interactions are governed by excited electronic states within the absorbing or emitting medium at the quantum level. This is what defines the field of optoelectronics – the study of the connection between materials’ electronic and optical properties, in particular towards functional devices.

Since the isolation of monolayer graphene in 2004, a broad class of two-dimensional (2D) materials has emerged, exhibiting remarkable electrical and optical properties. These unique characteristics make them highly promising candidates for next-generation optoelectronic devices.

In this talk, I will present recent results on how especially 2D semiconductors can be utilized for a variety of optoelectronic applications. I will also discuss how engineered optical nanostructures can be leveraged to enhance light-matter interaction and enable new functionalities.
