Temperature Effect on Charge-state Transition Levels of Defects in Semiconductors
Shuang Qiao, Yu-Ning Wu, Xiaolan Yan +3
Defects are crucial in determining the overall physical properties of semiconductors. Generally, the charge-state transition level (TEL), one of the key physical quantities that de…
Mott insulator tuning via structural distortion in monolayer 1T-NbSe2
Zhen-Yu Liu, Shuang Qiao, Qiao-Yin Tang +8
Mott state in 1T-TaS2 is predicted to host quantum spin liquids (QSL). However, its insulating mechanism is controversial due to complications from interlayer coupling. Here, we st…
Giant renormalization of correlation strength in 1T-TaS2 by lattice vibration
Li Cheng, Shunhong Zhang, Shuang Qiao +3
The lattice thermodynamics of a 1T-TaS2 layer, e.g. the spontaneous formation of a sqrt13*sqrt13 commensurate charge density wave (CCDW) and vibrations around the equilibrium posit…
Renormalization of the Mott gap by lattice entropy: The case of 1T-TaS2
Li Cheng, Shunhong Zhang, Shuang Qiao +3
In many transition-metal oxides and dichalcogenides, the electronic and lattice degrees of freedom are strongly coupled, giving rise to remarkable phenomena, such as metal-insulato…
A protonated brownmillerite electrolyte for superior low-temperature proton conductivity
Nianpeng Lu, Yujia Wang, Shuang Qiao +18
Design novel solid oxide electrolyte with enhanced ionic conductivity forms one of the Holy Grails in the field of materials science due to its great potential for wide range of en…
The role of interstitial hydrogen in SrCoO antiferromagnetic insulator
Li Liang, Shuang Qiao, Shunhong Zhang +2
Hydrogen exhibits qualitatively different charge states depending on the host material, as nicely explained by the state-of-the-art impurity-state calculation. Motivated by a recen…
Orbital-driven Mottness collapse in 1T-TaS2-xSex transition metal dichalcogenide
Shuang Qiao, Xintong Li, Naizhou Wang +9
The vicinity of a Mott insulating phase has constantly been a fertile ground for finding exotic quantum states, most notably the high Tc cuprates and colossal magnetoresistance man…
