To meet the fast-expanding needs of thermoelectric cooling for high heat flux systems, high-performance devices must be constructed with materials possessing both properties and mechanical strength. However, synergistic improvement is challenging because anisotropic thermal electrical transports in layered Van der Waals structure Bi2Te3, particularly n-type Bi2(TexSe1-x)3 material. The hot extrusion (HE) technique was believed as most efficient approach to decoupling Bi2Te3. mechanism...
Molecular orbital tomography (MOT) based on high-order-harmonic generation opens a way to track the molecular electron dynamics or even follow chemical reaction.
