Cold source field-effect transistor with type-III band-aligned HfS/WTe heterostructure
Shujin Guo, Qing Shi, Deping Guo +4
The cold source field-effect transistor (CSFET) is promising for reducing power dissipation in integrated circuits by engineering the density of states at the injecting source. Exi…
Kinetically accessible 1D magnetic chains of transition-metal chalcogenides and halides on van der Waals surfaces
Canbo Zong, Deping Guo, Renhong Wang +9
One-dimensional (1D) chains offer unique opportunities for nanoelectronics and spintronics, yet their experimental realization remains challenging because 1D motifs are often therm…
Mechanically and electrically switchable triferroic altermagnet in a pentagonal FeO2 monolayer
Deping Guo, Jiaqi Dai, Renhong Wang +2
Two-dimensional multiferroics promise low-power, multifunctional devices, yet the intrinsic coexistence and mutual control of three coupled ferroic orders in a single layer remains…
Electric-Field-Tunable Luttinger compensated antiferromagnetism in double CrCl2 chains
Deping Guo, Weihan Zhang, Canbo Zong +2
Luttinger compensated antiferromagnets (LcAFMs), combining spin polarization with vanishing net magnetization, offering distinct advantages for next-generation spintronic applicati…
Tunable altermagnetism via inter-chain engineering in parallelassembled atomic chains
Deping Guo, Canbo Zong, Weihan Zhang +3
Altermagnetism has recently drawn considerable attention in three- and twodimensional materials. Here, we extend this concept to quasi-one-dimensional (Q1D) monolayers assembled fr…
Evidence of Ferroelectricity in an Antiferromagnetic Vanadium Trichloride Monolayer
Jinghao Deng, Deping Guo, Yao Wen +12
A reduced dimensionality of multiferroic materials is highly desired for device miniaturization, but the coexistence of ferroelectricity and magnetism at the two-dimensional limit…
