TSOM Method for Nanoelectronics Dimensional Metrology

November 18, 2011
Author(s)
Ravikiran Attota
Through-focus scanning optical microscopy (TSOM) is a relatively new method that transforms conventional optical microscopes into truly three-dimensional metrology tools for nanoscale to microscale dimensional analysis. TSOM achieves this by acquiring and

DEMONSTRATION OF AN INTEGRATED MICRO CRYOGENIC COOLER AND MINIATURE COMPRESSOR FOR COOLING TO 200 K

Ryan J. Lewis, Mu Hong Lin, Yunda Wang, Jill Cooper, Peter E. Bradley, Ray Radebaugh, Marcia L. Huber, Yung-Cheng Lee
Joule-Thompson (J-T) based micro cryogenic coolers (MCCs) are attractive because they can provide the cryogenic temperatures needed for small electronic devices while having a low cost and small volumetric footprint. A compressor is a major part of a

High-resolution single-mode fiber-optic distributed Raman sensor for absolute temperature measurement using superconducting nanowire single-photon detectors

Michael G. Tanner, Shellee D. Dyer, Burm Baek, Robert Hadfield, Sae Woo Nam
We demonstrate a distributed fiber Raman sensor for absolute temperature measurement with spatial resolution on the order of 1 cm at 1550 nm wavelength in single mode fiber using superconducting nanowire single photon detectors. Rapid measurements are

Minimizing damage during FIB-TEM sample preparation of soft materials

November 17, 2011

Nabil Bassim, Bradley De Gregorio, A. D. Kilcoyne, Keana Scott, Tsngming Chou, S. Wirick, George Cody, Rhonda Stroud
Although focused ion beam (FIB) microscopy has been used successfully for milling patterns and creating ultra-thin transmission electron microscopy (TEM) sections of polymers and other soft materials, little has been documented regarding FIB-induced damage

Self-Repairing Complex Helical Columns Generated via Kinetically Controlled Self-Assembly of Dendronized Perylene Bisimides

Virgil Percec, Steven Hudson, Mihai Peterca, Pawaret Leowanawat, Emad Aqad, Robert Graf, Hans -. Spiess, Xiangbing Zeng, Goran Ungar, Paul A. Heiney
The dendronized perylene 3,4:9,10-tetracarboxylic acid bisimide (PBI) (3,4,5)12G1-3-PBI was recently shown to self-assemble in a complex helical column containing tetramers of PBI as the basic repeat unit. The tetramers contain a pair of two molecules

XML Validation Website: A User's Guide
