Lab-based multi-wavelength EUV diffractometry for critical dimension metrology

Author(s)
Bryan Barnes, Aaron Chew, Nicholas Jenkins, Yunzhe Shao, Martin Sohn, Regis Kline, Daniel Sunday, Purnima Balakrishnan, Thomas Germer, Steven Grantham, Clay Klein, Stephanie Moffitt, Eric Shirley, Henry Kapteyn, MARGARET MURNANE
Background: The industry is developing extreme-ultraviolet wavelength (EUV) techniques to measure critical dimensions (CDs) in logic fabrication. As nascent

Extensive Hydrogen Incorporation is not Necessary for Superconductivity in Topotactically Reduced Nickelates

Purnima Balakrishnan, Dan Segedin, Lin Chow, P. Quarterman, Shin Muramoto, Mythili Surendran, Ranjan Patel, Harrison LaBollita, Grace Pan, Qi Song, Yang Zhang, Ismail El Baggari, Koushik Jagadish, Yu-Tsun Shao, Berit Goodge, Lena Kourkoutis, Srimanta Middey, Antia Botana, Jayakanth Ravichandran, A. Ariando, Julia A. Mundy, Alexander Grutter
A key open question in the study of layered superconducting nickelate films is the role that hydrogen incorporation into the lattice plays in the appearance of

Coexistence of Superconductivity and Antiferromagnetism in Topological Magnet MnBi2Te4 Films

Author(s)
Wei Yuan, Zi-Jie Yan, Hemian Yi, Zihao Wang, Stephen Paolini, Yi-Fan Zhao, Ling-Jie Zhou, Annie G. Wang, Ke Wang, Thomas Prokscha, Zaher Salman, Andreas Suter, Purnima Balakrishnan, Alexander Grutter, Laurel E. Winter, John Singleton, Moses H. Chan, Cui-Zu Chang
The interface of two materials can harbor unexpected emergent phenomena. One example is interface-induced superconductivity. In this work, we employ molecular

Vertically Graded FeNi Alloys with Low Damping and a Sizeable Spin-Orbit Torque

Author(s)
Rachel Maizel, Shuang Wu, Purnima P. Balakrishnan, Alexander Grutter, Christy Kinane, Andrew Caruana, Prabandha Nakarmi, Bhuwan Nepal, David Smith, Youngmin Lim, Juila Jones, Wyatt Thomas, Jing Zhao, F. Michel, Tim Mewes, Satoru Emori
Energy-efficient spintronic devices require a large spin-orbit torque (SOT) and low damping to excite magnetic precession. In conventional devices with heavy-me

Reduction-Induced Magnetic Behavior in LaFeO3-δ Thin Films
