Abstract: 

Light’s interaction with matter gives rise to a large variety of useful technological applications, e.g., photovoltaics, photodetectors, lasers, etc. Fundamentally, light and matter’s interaction are driven by excited electronic states in the absorbing/emitting material. This is also what forms the basis of the field of optoelectronics – that a material’s optical properties can be controlled via electronics, and vice versa. A huge variety of 2D materials have emerged since the successful isolation of monolayer graphene in 2004, and they have displayed both remarkable electrical and optical properties. This makes them of great interest to be studied for potential optoelectronic device applications. In the talk I will cover recent results on several optoelectronic devices in a variety of material platforms, and how engineered optical nanostructures can be utilized to enhance their performance.
