Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2

Small, EarlyView.
The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...
