Inversion of quartz solid solutions at cryogenic temperatures

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 ...

Dielectric properties of PbNb2O6 ferroelectric ceramics at cryogenic temperatures

Mechanical quality factor of a sapphire fiber at cryogenic temperatures

A mechanical quality factor of 1.1× 107 was obtained for the 199Hz bending vibrational mode in a monocrystalline sapphire fiber at 6K. Consequently, we confirm that pendulum thermal noise of cryogenic mirrors used for gravitational wave detectors can be reduced by the sapphire fiber suspension.

Operation of SiGe bipolar technology at cryogenic temperatures

The recent introduction of silicon-germanium (SiGe) alloys has proven exceptionally promising for achieving excellent bipolar transistor performance at cryogenic temperatures, while maintaining the cost and yield advantages traditionally associated with silicon (Si) manufacturing. In this paper we review the features of silicon-germanium heterojunction bipolar transistors (SiGe HBTs) which make...
