X-Ray Metrology of Nanowire/ Nanosheet FETs for Advanced Technology Nodes

March 30, 2020
Author(s)
Madhulika S. Korde, Regis J. Kline, Daniel Sunday, Nick Keller, Subhadeep Kal, Cheryl Alix, Aelen Mosden, Alain C. Diebold
The three-dimensional architectures for field effect transistors (FETs) with vertical stacking of Gate-all-Around Nanowires provide a pathway to increased device density and superior electrical performance. However, the transition from research into

A Microporous Metal-Organic Framework with Naphthalene Diimide Groups for High Methane Storage

Yingxiang Ye, Rui-Biao Lin, Hui Cui, Ali Alsalme, Wei Zhou, Taner N. Yildirim, Zhangjing Zhang, Shengchang Xiang, Banglin Chen
We reported a microporous MOF FJU-101 with open naphthalene diimide functional groups for room temperature (RT) high methane storage. At RT and 65 bar, the total volumetric CH 4 storage capacity of 212 cm -3 in FJU-101a is significantly higher than the

Wear comparison of critical dimension-atomic force microscopy tips

March 28, 2020
Author(s)
Ndubuisi G. Orji, Ronald G. Dixson, Ernesto Lopez, Bernd Imer
Nanoscale wear affects the performance of atomic force microscopy (AFM)-based measurements for all applications including process control, nanoelectronics characterization and topography measurements. As such, methods to prevent or reduce AFM tip wear is

A Single Amino Acid Substitution Alters ClpS Binding Specificity

March 27, 2020
Author(s)
Christina Bergonzo, Jennifer A. Tullman, Kunal Dharmadhikari, Emily Samuels, Makenzie Christensen
ClpS is a small protein currently under development as a probe for detecting specific N-terminal amino acids of peptides. In order for ClpS to be used in this manner, it is important to understand the structural reasons for how and why ClpS recognizes

Atom Probe Tomography using Extreme-Ultraviolet Light

March 27, 2020
Author(s)
Luis Miaja Avila, Ann C. Chiaramonti Debay, Benjamin W. Caplins, David R. Diercks, Brian Gorman, Norman A. Sanford
We present a different approach to laser-assisted atom probe tomography, where instead of using a near-UV laser for inducing a thermal transient, we use an extreme-ultraviolet coherent light source to trigger eld ion emission at the tip's apex. The use of

Design and Characterization of an Architecturally Perfect Family of Linear Low-Density Polyethylenes (LLDPEs) by Multi-Detector Size Exclusion Chromatography

March 27, 2020
Author(s)
Sara V. Orski, Luke Kassekert, Wesley Farrell, Grace A. Kenlaw, Marc Hillmyer, Kathryn L. Beers
Separations of commercial polyethylenes, which often involve mixtures and copolymers of linear, short-chain, and long-chain branched chains, can be very challenging to optimize as species with similar hydrodynamic sizes or solubility often co-elute in

Frequency-comb spectroscopy on pure quantum states of a single molecular ion

March 27, 2020
Author(s)
Chin-wen Chou, Alejandra L. Collopy, Christoph Kurz, Yiheng Lin, Michael E. Harding, Philipp N. Plessow, Tara M. Fortier, Scott A. Diddams, Dietrich G. Leibfried, David R. Leibrandt
Spectroscopy is a powerful tool for studying molecular properties and is commonly performed on large thermal ensembles of molecules that are perturbed by motional shifts and interactions with the environment and one another, resulting in convoluted spectra

Low-field magnetic resonance imaging of roots in intact clayey and silty soils

Author(s)
Mark S. Conradi, Stephen A. Altobelli, Dean O. Kuethe, Matthew S. Rosen, Neha Koonjoo, Bo Zhu, Karl Stupic, William L. Rooney, John E. Mullet, Brock Weers, G. Cody Bagnall, Haly Neely, Eiichi Fukushima, Cristine Morgan
The development of a robust method to non-invasively visualize root morphology in natural soils has been hampered by the opaque nature, chemical composition, and physical structure of soils. We describe here a novel technology—low field magnetic resonance

On Selecting Channel Parameters for Public Safety Network Applications in LTE Direct

March 26, 2020
Author(s)
Siyuan Feng, Hyong-Ah Choi, David W. Griffith, Richard A. Rouil
The Third Generation Partnership Project (3GPP) defines various pre-configured channel parameters for the Long- Term Evolution (LTE) Device-to-Device (D2D) communications with Physical Sidelink (SL) Channels. In this paper, we investigate the impacts of
