Refractive Index of ZnSe at Cryogenic Temperatures†

This report describes an extensive data set on the refractive index of ZnSe that provides full high resolution coverage of the CRIRES operating range in both wavelength and temperature. By combining our prototype instrument model of CRIRES with these data our project to provide wavelength calibration for IR Echelle spectrographs (WIRE) has reached an important milestone and is ready to support ...

[1011] Scanning Thermal Microscopy on 2D Materials at cryogenic temperatures

Thermal transport in Graphene is of great interest due to its high thermal conductivity, for both fundamental research and future applications such as heat dissipation in electronic devices. Although, the thermal conductivity of graphene can reduce depending on the coupling to the substrate [1]. In this work, we report high-resolution imaging of nanoscale thermal transport in single and few lay...

Anisotropic longitudinal electronic relaxation affects DNP at cryogenic temperatures.

We report the observation of anisotropic longitudinal electronic relaxation in nitroxide radicals under typical dynamic nuclear polarization conditions. This anisotropy affects the efficiency of dynamic nuclear polarization at cryogenic temperatures of 4 K and high magnetic fields of 6.7 T. Under our experimental conditions, the electron paramagnetic resonance spectrum of nitroxides such as TEM...
