Gate Voltage Tunable Second Harmonic Generation in Mono- and Bi-layer Black Phosphene
Yan Meng, Kainan Chang, Yanyan Qian +2
Black phosphorene (BP) has emerged as a promising platform for tunable nonlinear photonics due to its layer-dependent bandgap, high carrier mobility, and remarkable in-plane anisot…
Harmonic generation of graphene quantum dots in Hartree-Fock approximation
Kainan Chang, Ying Song, Yuwei Shan +1
We theoretically investigate harmonic generation in graphene quantum dots under linearly polarized optical pulses, focusing on excitonic effects. Combining the tight-binding model…
Gate voltage induced injection and shift currents in AA- and AB-stacked bilayer graphene
Ze Zheng, Kainan Chang, Jin Luo Cheng
Generating photogalvanic effects in centrosymmetric materials can provide new opportunities for developing passive photodetectors and energy harvesting devices. In this work, we in…
Optical Coherent Injection of Carrier and Current in Twisted Bilayer graphene
Ze Zheng, Ying Song, Yu Wei Shan +2
We theoretically investigate optical injection processes, including one- and two-photon carrier injection and two-color coherent current injection, in twisted bilayer graphene with…
