Bulk Photovoltaic Effects in Helimagnets
Chunmei Zhang, Jian Zhou
The bulk photovoltaic (BPV) effect that converts light into electric current is highly sensitive to the system symmetry and its electronic Bloch wavefunction. To create a sizable n…
Non-centrosymmetric, transverse structural modulation in SrAl4, and elucidation of its origin in the BaAl4 family of compounds
Sitaram Ramakrishnan, Surya Rohith Kotla, Hanqi Pi +13
At ambient conditions SrAl4 adopts the BaAl4 structure type with space group I4/mmm. It undergoes a charge-density-wave (CDW) transition at TCDW = 243 K, followed by a structural t…
Gate-tunable multiband transport in ZrTe5 thin devices
Yonghe Liu, Hanqi Pi, Kenji Watanabe +7
Interest in ZrTe5 has been reinvigorated in recent years owing to its potential for hosting versatile topological electronic states and intriguing experimental discoveries. However…
Magnetic bulk photovoltaic effect as a probe of magnetic structures of
Hanqi Pi, Shuai Zhang, Hongming Weng
The bulk photovoltaic effect (BPVE) is a second-order optical process in noncentrosymmetric materials that converts the light into DC currents. BPVE is classified into shift curren…
