A Universal Description of Workfunction
Zeyu Jiang, Damien West, Shengbai Zhang
At the surfaces of materials, the bulk symmetry of the charge density is broken and electron spill-out into the vacuum region creates a surface dipole. Such spill-out has been hist…
Polarization at the Nanoscale
Ke Yang, Zeyu Jiang, Duk-Hyun Choe +2
Modern polarization theory yields surface bound charge associated with spontaneous polarization of bulk. However, understanding polarization in nano systems also requires a proper…
Realization of AlSb in the double layer honeycomb structure: a robust new class of two-dimensional material
Le Qin, Zhi-Hao Zhang, Zeyu Jiang +10
Exploring new two-dimensional (2D) van der Waals (vdW) systems is at the forefront of materials physics. Here, through molecular beam epitaxy on graphene-covered SiC(0001), we repo…
Vector Potential and Surface Magnetic Field in Magnetoelectric Antiferromagnetic Materials
Zeyu Jiang, Damien West, Shengbai Zhang
A general formula for the average vector potential of bulk periodic systems is proposed and shown to set the boundary conditions at magnetic interfaces. For antiferromagnetic mater…
Spin-Triplet Excitonic Insulator: The Case of Graphone
Zeyu Jiang, Wenkai Lou, Yu Liu +5
While various excitonic insulators have been studied in the literature, due to the perceived too-small spin splitting, spin-triplet excitonic insulator is rare. In two-dimensional…
Electronic structure of molecular beam epitaxy grown 1T-MoTe film and strain effect
Xue Zhou, Zeyu Jiang, Kenan Zhang +5
Atomically thin transition metal dichalcogenide films with distorted trigonal (1T) phase have been predicted to be candidates for realizing quantum spin Hall effect. Growt…
Half Excitonic Insulator: A Single-Spin Bose-Einstein Condensate
Zeyu Jiang, Yuanchang Li, Wenhui Duan +1
First-principles calculations reveal an unusual electronic state (dubbed as half excitonic insulator) in monolayer 1T-MX2 (M = Co, Ni and X = Cl, Br). Its one spin channel has a ma…
Realizing intrinsic excitonic insulator by decoupling exciton binding energy from the minimum band gap
Zeyu Jiang, Yuanchang Li, Shengbai Zhang +1
Direct-gap materials hold promises for excitonic insulator. In contrast to indirect-gap materials, here the difficulty to distinguish from a Peierls charge density wave is circumve…
