Temperature Dependent Low-Frequency Noise Characteristics of NiO/GaO p-n Heterojunction Diodes

Subhajit Ghosh, Dinusha Herath Mudiyanselage, Fariborz Kargar +3

We report on the temperature dependence of the low-frequency electronic noise in NiO/GaO p-n heterojunction diodes. The noise spectral density is of the 1/f-type near r…

Discovery of Terahertz Second Harmonic Generation from Lightwave Acceleration of Symmetry--Breaking Nonlinear Supercurrents

C. Vaswani, C. Sundahl, M. Mootz +11

We report terahertz (THz) second harmonic generation (SHG) in superconductors (SC) with inversion symmetric equilibrium states that forbid even-order nonlinearities. Such SHG signa…

Ultrafast Control of Excitonic Rashba Fine Structure by Phonon Coherences in a Metal Halide Perovskite CHNHPbI

Z. Liu, C. Vaswani, X. Yang +14

We discover hidden Rashba fine structure in CHNHPbI and demonstrate its quantum control by vibrational coherence through symmetry-selective vibronic (electron-phonon) c…
