Abstract

In this talk, I shall discuss the probing and strong tunability of inter-layer excitons that are trapped in a moire potential well created through a hetero-bilayer. I shall show that these excitons trapped at different energy states inside the moire well exhibit surprising anomalous Stark shift and strong dipolar repulsion. Time permitting, I shall also discuss about a novel excitonic state in a hetero-trilayer - a moire-trapped quadrapolar exciton and it's spectroscopic signatures.
