A compact, transportable, Josephson voltage standard, first reported at CPEM96, has now been field tested and has had ten months of use as a primary standard by National Aeronautics and Space Administration (NASA) laboratories. We discuss here its

We have developed a Josephson voltage standard that produces intrinsically stable voltages that are programmable of 32 768 SNS (superconductor-normal-superconductor) Josephson junctions. The output can source or sink up to 2 mA and thus has high noise

We have investigated the performance of VO 2 microbolometers biased on the semiconducting-metal phase transition with negative electrothermal feedback. We deposited crystalline thin films of phase-pure VO 2, patterned these films into useful test

Dipole antennas designed for operation at 10 5m wavelength have been fabricated by optical lithography and their properties measured by detection of CO 2 laser rediation in integrated thin-film bolometers. We find a remarkably strong increase in cross
Research on the electronic applications of organic semiconductors is growing rapidly, and both polymeric and small molcule organics are being used in the fabrication of LEDs, transistors, and biological/chemical sensors. As a part of the chemical
The Electricity Division of the National Institute of Standards and Technology is developing revised performance standards for hand-held (HH) and walk-through (WT) metal weapon detectors, test procedures and systems for these detectors, and a detection

Microwave-frequency (rf) power-dependence measurements performed on thin-film Yba 2Cu 3O^d7-δ grain boundaries engineered on sapphire bicrystal substrates with misorientation angles of θ=20, 50, 100, and 240 are presented. The data are compared to
This bibliography lists the publications of the staff of the Electromagnetic Technology Division of NIST during the period from January 1970 through July 1999. The bibliography is divided into two general sections: (a) Cryoelectronic Metrology and (b)
