Chen Group

Lab of Advanced Quantum Materials

We grow revolutionary low dimensional quantum materials and structures where quantum confinement and coherence coupling find collective macroscopic manifestations by molecular beam epitaxy (MBE). We explore, understand, and control the fundamental physical properties by spin-, angle-resolved photoemission spectroscopy (Spin-ARPES).

Highlights


News

2025.04, We revealed d-p hybridization strength can stablize the Mott phase in monolayer 1T-MX2 (M = Ta, Nb; X = Se, S) by tuning the bandwidth of the flat band. The paper has been published in Nature Communications. 科研进展 ！

2025.01, We observed the spinon-holon continuum spectrum and quantum spin liquid behavior in monolayer 1T-TaS2. The paper has been published in Physical Review Letters. 科研进展 ！

2024.01, We discovered atomically thin HfTe2 as an ideal excitonic insulator with a metal-insulator transition of purely electronic origin. A small amount of n-type doping significantly increased the Tc, which reaches maximum when carrier density is lowest around the Fermi level. The paper has been published in Nature Physics. 科研进展 ！ Phys.org
