It is well known that quantum coherence and interference are basic mechanisms for controlling the optical responses of atomic and solid-state media. Over the past few years, several interesting ...

We have studied two-dimensional absorption and gain spectrum in an asymmetric semiconductor triple-coupled-quantum-well (TCQW) nanostructure. Four subband transitions are coupled by using four ...

Highly enhanced UV absorption and light emission of monolayer WS2 through hybridization with Ti2N MXene quantum dots and g-C3N4 quantum dots This work represents a significant advancement in the field ...

Quantum wells are nanoscale structures that confine the motion of electrons or holes in one dimension, while allowing free movement in the other two dimensions. They are formed by sandwiching a thin ...
