Transition metal dichalcogenides (TMDCs) are an emerging and promising class of materials comprised of a transition metal atomic layer sandwiched between two layers of chalcogen atoms. These 2D materials have received considerable ...
Light can excite electron and hole pairs inside semiconducting materials. If the attraction between a negatively charged electron and a positively charged hole (the antiparticle of electron in solid state physics) is strong, ...
A quasiparticle called an exciton—responsible for the transfer of energy within devices such as solar cells, LEDs, and semiconductor circuits—has been understood theoretically for decades. But exciton movement within ...
