Detrapping and retrapping of free carriers in nominally pure single crystal GaP, GaAs and 4H-SiC semiconductors under light illumination at cryogenic temperatures
David Mouneyrac, John G. Hartnett, Jean-Michel Le Floch +3
We report on extremely sensitive measurements of changes in the microwave properties of high purity non-intentionally-doped single-crystal semiconductor samples of gallium phosphid…
Single Crystal Sapphire at milli-Kelvin Temperatures: Observation of Electromagnetically Induced Thermal Bistability in High Q-factor Whispering Gallery Modes
Daniel L. Creedon, Michael E. Tobar, Jean-Michel Le Floch +2
Resonance modes in single crystal sapphire (-AlO) exhibit extremely high electrical and mechanical Q-factors ( at 4K), which are important characteristics…
Cryogenic Sapphire Oscillator using a low-vibration design pulse-tube cryocooler: First results
John G. Hartnett, Nitin R. Nand, Chao Wang +1
A Cryogenic Sapphire Oscillator has been implemented at 11.2 GHz using a low-vibration design pulse-tube cryocooler. Compared with a state-of-the-art liquid helium cooled CSO in th…
