In Search of Better Pressure Standards

Author(s)
Jay H. Hendricks, Jacob E. Ricker, Patrick F. Egan, Gregory F. Strouse
Based on highly accurate optical interferometry and fundamental quantum calculations, researchers at the National Institute of Standards and Technology (NIST)

Development of an EUVL collector with infrared radiation suppression

Author(s)
Steven E. Grantham, Mike Kriese, Yuriy Platonov, Bodo Ehlers, Licai Jiang, Jim Rodriguez, Mueller Ulrich, Shayna khatri, Adam Magruder, Charles S. Tarrio
Laser-produced plasma (LPP) sources for extreme ultraviolet lithography (EUVL) systems utilize CO2 lasers operating with wavelength 10.6μm. Since multilayer

Author(s)
Charles S. Tarrio, Steven E. Grantham, Thomas A. Germer, Jack C. Rife, Thomas B. Lucatorto, Mike Kriese, Yuriy Platonov, Licai Jiang, Jim Rodriguez
The NIST Extreme Ultraviolet (EUV) Reflectometry Facility was designed in the 1990s to accommodate the largest multilayer optics envisioned at that time

Phase Transitions and Magnetocaloric Effect in Mn3Cu0.89Nd0.96^

Author(s)
Jun Yan, Ying Sun, Hui Wu, Qingzhen Huang, Cong Wang, Zaixing Shi, Sihao Deng, Kewen Shi, Huiqing Lu, Lihua Chu
We report the large magnetic entropy change observed in the antiperovskite Mn 3Cu 0.89N 0.96. Based in the heat flow peak measured by differential scanning

Elliptic Curves arising from Brahmagupta Quadrilaterals

Author(s)
Farzali Izadi, Foad Khoshnam, Dustin Moody, Arman Zargar
A Brahmagupta quadrilateral is a cyclic quadrilateral whose sides, diagonals, and area are all integer values. In this article, we characterize the notions of

Characterization of Buried Structure in Directed Self Assembly Block Copolymers

Author(s)
Daniel F. Sunday, Matthew R. Hammond, Chengqing C. Wang, Wen-Li Wu, Dean M. DeLongchamp, Regis J. Kline, Melia Tjio, Joy Cheng, Jed W. Pitera
The directed self assembly (DSA) of block copolymers (BCP) can multiply or subdivide the pitch of a lithographically defined chemical or topological pattern and

Resistive Flow in a Weakly Interacting Bose-Einstein condensate

Author(s)
Fred Jendrzejewski, Stephen P. Eckel, Noel Murray, Calib Lanier, Mark Edwards, Christopher J. Lobb, Gretchen K. Campbell
We report the direct observation of resistive flow through a weak link in a weakly interacting atomic Bose- Einstein condensate (BEC). Two weak links separate
