CODATA values of the fundamental physical constants

Ongoing
CODATA recommended values of the constants Database of references for data on the constants Publications: Reviews of Modern Physics ( 1998) ( 2002) ( 2006) ( 2010) ( 2014) Journal of Physical and Chemical Reference Data ( 1998) ( 2006) ( 2010) Resource Letter FC-1: The physics of fundamental
EUV optics degradation in space

Degradation of extreme-ultraviolet optics

Ongoing
The primary degradation process in EUVL tools and satellite instruments begins by the adsorption of water or carbonaceous molecules from the vacuum environment onto the optic surface. The optic is damaged if the molecule undergoes photon-stimulated decomposition before it can (reversibly) thermally

Extreme Ultraviolet Detector Calibration Service

Ongoing
The National Institute of Standards and Technology (NIST) has a wide variety of programs for the calibration of instruments and components for space-based research in the extreme ultraviolet (EUV). Many of these programs have been in existence since the 1960s, and have provided calibration support
Reflectance of two materials

Extreme ultraviolet optical constants

Ongoing
Measurements of EUV optical constants are often made by measuring the absorption or near-normal-incidence reflectivity, then performing transforms to obtain both the real and imaginary parts of the index. These sorts of measurements have considerable uncertainty because they require knowledge of
EUV Relectivity

Metrology for extreme ultraviolet lithography

Ongoing
Patterning with light 13 nm brings a host a new challenges Light at 13 nm is well within the vacuum ultraviolet, where radiation is strongly absorbed by all materials. This requires that the technology take place in vacuum and rely on mirrors rather than lenses. Moreover generating sufficient
A 3" wafer is seen concentric with the lower plasma electrode.

Precision Materials for Quantum Devices

Ongoing
MBE System Our fabrication system is composed of ultra-high vacuum (UHV) chambers that support the in-vacuum exchange of 75 mm wafers without exposure to air as seen in Figure 1. These chambers are: (1) a deposition chamber with electron gun deposition, UHV compatible sputter guns, in situ shadow

Precision Measurement Grants Program

Ongoing
If funding is available, two new grants in the amount of $50,000 per year will be awarded for the initial period of October 1 through September 30 of the following year. Each award may be continued for up to two additional years; however, future or continued funding will be at the discretion of NIST

Quantum Physics Theory

Ongoing
The scope of the work ranges from calculations of QED effects in atoms to detailed studies of photon wave functions.
