Probing NV and SiV charge state dynamics using high-voltage nanosecond pulse and photoluminescence spectral analysis
Artur Pambukhchyan, Sizhe Weng, Indu Aravind +2
Nitrogen-vacancy (NV) and silicon-vacancy (SiV) color defects in diamond are promising systems for applications in quantum technology. The NV and SiV centers have multiple charge s…
Mid-wave and Long-wave IR Linear Dichroism in a Hexagonal Perovskite Chalcogenide
Shanyuan Niu, Huan Zhao, Yucheng Zhou +6
Mid-wave infrared (IR) and long-wave IR spectral ranges are of growing interest in various applications such as thermal imaging, thermography-based remote sensing, and night vision…
Ideal Bandgap in a 2D Ruddlesden-Popper Perovskite Chalcogenide for Single-junction Solar Cells
Shanyuan Niu, Debarghya Sarkar, Kristopher Williams +12
Transition metal perovskite chalcogenides (TMPCs) are explored as stable, environmentally friendly semiconductors for solar energy conversion. They can be viewed as the inorganic a…
Broadband Terahertz Modulation in Electrostatically-doped Artificial Trilayer Graphene
Ioannis Chatzakis, Zhen Li, Alex Benderskii +1
We report a terahertz optical modulator consisting of randomly stacked trilayer graphene (TLG) deposited on an oxidized silicon substrate by means of THz- Time Domain Spectroscopy…
Optical Determination of Electron-Phonon Coupling in Carbon Nanotubes
Y. Yin, A. Vamivakas, A. Walsh +4
We report on an optical method to directly measure electron-phonon coupling in carbon nanotubes by correlating the first and second harmonic of the resonant Raman excitation profil…
Intrinsic Optical Transition Energies in Carbon Nanotubes
Yan Yin, Stephen Cronin, Andrew Walsh +7
Intrinsic optical transition energies for isolated and individual single wall carbon nanotubes grown over trenches are measured using tunable resonant Raman scattering. Previously…
