Optical Stark metrology of CdSe quantum dots: Reconciling the size-dependent oscillator strength with theory
Yanhao Tang, Mersedeh Saniepay, Chenjia Mi +2
The effective mass approximation (EMA) predicts large, nearly size-independent exciton oscillator strengths in quantum confined semiconductors. Yet, experimental reports…
Layer- and Frequency-Dependent Second Harmonic Generation in Reflection from GaSe Atomic Crystals
Yanhao Tang, Krishna C. Mandal, John A. McGuire +1
We report optical second-harmonic generation (SHG) in reflection from GaSe crystals of 1 to more than 100 layers using a fundamental picosecond pulsed pump at 1.58 eV and a superco…
Optical Spin Polarization Dynamics in GaSe Nanoslabs
Yanhao Tang, Wei Xie, Krishna C. Mandal +2
We report nearly complete preservation of "spin memory" between optical absorption and photoluminescence (PL) in nanometer slabs of GaSe pumped with up to 0.2 eV excess energy. At…
Exciton spin dynamics in GaSe
Yanhao Tang, Wei Xie, Krishna C. Mandal +2
We analyze exciton spin dynamics in GaSe under nonresonant circularly polarized optical pumping with an exciton spin-flip rate-equation model. The model reproduces polarized time-d…
Linearly polarized remote-edge luminescence in GaSe nanoslabs
Yanhao Tang, Wei Xie, Krishna C. Mandal +2
We report highly linearly polarized remote luminescence that emerges at the cleaved edges of nanoscale gallium selenide slabs tens of micrometers away from the optical excitation s…
Near Unity Optical Spin Polarization in GaSe Nanoslabs
Yanhao Tang, Wei Xie, Krishna C. Mandal +2
We report nearly complete preservation of "spin memory" between optical absorption and photoluminescence (PL) in nanometer slabs of GaSe pumped with 0.2 eV excess energy. At cryoge…
