What Has Been Achieved:
Demonstrate ultrafast optical melting of trimer superstructure in layered 1T′-TaTe2.
Importance of the Achievement:
Harnessing emergent orders in quantum materials has the potential to revolutionize energy and information Technologies. Quasi-two-dimensional transition-metal dichalcogenides are a key platform for exploring emergent nanoscale phenomena arising from complex interactions. This work establishes TaTe2 as a promising material for optical control, motivating examination of concomitant electronic dynamics for device applications.
Unique Feature(s) of the MIP that Enabled this Achievement:
The 2DCC bulk growth team has not only expertise of crystal growth using various methods, but also capacity of structure and property characterization. Such combination of material growth and characterization enables the 2DCC researchers to grow novel quantum materials which can meet needs of various experiments and attract new users. This collaborative work directly benefits this unique feature of the 2DCC.
