Symmetry-breaking and spin-blockage effects on carrier dynamics in single-layer tungsten diselenide
Symmetry-breaking and spin-blockage effects on carrier dynamics in single-layer tungsten diselenide
Understanding carrier creation and evolution in materials initiated by pulsed optical excitation is central to developing ultrafast optoelectronics. We demonstrate herein that the dynamic response of a system can be drastically modified when its physical dimension is reduced to the atomic scale, the ultimate limit of device miniaturization. A comparative …
