Semiconducting transition metal dichalcogenides (TMDCs)

The high degree of control over the electronic properties and strong light-matter interactions in semiconducting TMDCs make them promising candidates for novel applications in photonics, optoelectronics and spintronics. For example, we can use laser pulses to switch the material from an insulating state to a metal state, on a sub-ps timescale, and directly measure the change in electronic band structure while this happens.
