Noise thermometry at ultra-low temperatures [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013
The options for primary thermometry at ultra-low temperatures are rather limited. In practice, most laboratories are using 195 Pt NMR thermometers in the microkelvin range. In recent years, current sensing direct current superconducting quantum interference devices (DC-SQUIDs) have enabled the use of noise ...

Ultra-Low Temperature Nuclear Magnetic Resonance [PDF]

IOP Conference Series: Materials Science and Engineering, 2017
Because NMR spectroscopy requests more sensitivity and more resolution, high-frequency and high-power microwave irradiation of electron spins in a magnetic field, Dynamic Nuclear Polarization (DNP) is becoming a common partner for fast sample spinning NMR experiments.

Novel thin film polymer foaming technique for low and ultra low-k dielectrics [PDF]

, 2001
The results presented show a novel route for the preparation of thin ultra-low-k polymer films based on commercial and "non-exotic" (non-expensive) polyimide by a foaming technique.

Thermometry at Ultra-Low Temperatures [PDF]

Japanese Journal of Applied Physics, 1987
A new millikelvin temperature scale is presented which is based in part on the constraint that the normal-phase specific heat of liquid 3He be linear in temperature with a proportionality constant taken from higher-temperature specific heat measurements.

An automated and versatile ultra-low temperature SQUID magnetometer [PDF]

, 2004
We present the design and construction of a SQUID-based magnetometer for operation down to temperatures T = 10 mK, while retaining the compatibility with the sample holders typically used in commercial SQUID magnetometers.

Ultra-low-temperature aqueous batteries [PDF]

Science, 2019
Energy Storage The development of efficient electrochemical energy storage systems is of prime importance for future energy management, which will be increasingly based on renewable energy sources. Aqueous rechargeable alkali-ion batteries are particularly attractive for large-scale implementations given their environmentally friendly components and ...

Angle-resolved Photoemission Spectroscopy At Ultra-low Temperatures [PDF]

Journal of Visualized Experiments, 2012
The physical properties of a material are defined by its electronic structure. Electrons in solids are characterized by energy (ω) and momentum (k) and the probability to find them in a particular state with given ω and k is described by the spectral function A(k, ω).

High Temperature Oxidation of Ultra-Low-Carbon Steel [PDF]

Defect and Diffusion Forum, 2006
An oxide scale layer always forms at the strip surface during the hot rolling process. Its properties have a large impact on surface quality. The most important features of the oxide layer are its thickness, composition, structure, adherence and coherence. Temperature, time and gas atmosphere determine the growth of oxide layers.

Integrated Electronic Transport and Thermometry at milliKelvin Temperatures and in Strong Magnetic Fields [PDF]

, 2011
We fabricated a He-3 immersion cell for transport measurements of semiconductor nanostructures at ultra low temperatures and in strong magnetic fields. We have a new scheme of field-independent thermometry based on quartz tuning fork Helium-3 viscometry ...

Terahertz Room-Temperature Photonic Crystal Nanocavity Laser

, 2007
We describe an efficient surface-passivated photonic crystal nanocavity laser, demonstrating room-temperature operation with 3-ps total pulse duration (detector response limited) and low-temperature operation with ultra-low-threshold near 9uW.Comment: 6 ...
