Strong bulk photovoltaic effect and second-harmonic generation in two-dimensional selenium and tellurium
Meijuan Cheng, Zi-Zhong Zhu, Guang-Yu Guo
Few-layer selenium and tellurium films have been recently prepared, and they provide a new platform to explore novel properties of two-dimensional (2D) elemental materials. In this…
Significant Second-Harmonic Generation and Bulk Photovoltaic Effect in Trigonal Selenium and Tellurium Chains
Meijuan Cheng, Xiaohong Shi, Shunqing Wu +1
One-dimensional selenium and tellurium crystalize in helical chainlike structures and thus exhibit fascinating properties. By performing first-principles calculations, we have rese…
Large Second-Harmonic Generation and Linear Electro-Optic Effect in Trigonal Selenium and Tellurium
Meijuan Cheng, Shunqing Wu, Zi-Zhong Zhu +1
Trigonal selenium and tellurium crystalize in helical chain-like structures and thus possess interesting properties such as current-induced spin polarization, gyrotropic effects an…
Large magneto-optical effects and magnetic anisotropy energy in two-dimensional CrGeTe
Yimei Fang, Shunqing Wu, Zi-Zhong Zhu +1
By performing systematic density functional calculations, here we study two relativity-induced properties of atomically thin ferromagnetic (FM) CrGeTe fil…
Exploration of tetrahedral structures in silicate cathodes using a motif-network scheme
Xin Zhao, Shunqing Wu, Xiaobao Lv +5
Using a motif-network search scheme, we studied the tetrahedral structures of the dilithium/disodium transition metal orthosilicates A2MSiO4 with A = Li or Na and M = Mn, Fe or Co.…
Vibrational modes and lattice distortion of a nitrogen-vacancy center in diamond from first-principles calculations
Jianhua Zhang, Cai-Zhuang Wang, Z. Z. Zhu +1
We investigate vibrational properties and lattice distortion of negatively charged nitrogen-vacancy (NV) center in diamond. Using the first-principles electronic structure calculat…
