Parmanand Sharma,Parmanand Sharma,Amita Gupta,K. V. Rao,Frank J. Owens,Renu Sharma,Rajeev Ahuja,J. M. Osorio Guillen,Börje Johansson,Börje Johansson,G. A. Gehring +10 more
TL;DR: The first observations of ferromagnetism above room temperature for dilute (<4 at%) Mn-doped ZnO semiconductors are reported, promising new spintronic devices as well as magneto-optic components.
Journal ArticleDOI
Room temperature spintronic material—Mn-doped ZnO revisited
TL;DR: In this article, the first observations of ferromagnetic ordering above room temperature for small atomic percentages of Mn doped in ZnO were reported, with an average moment of 0.16μ B per Mn ion.
Journal ArticleDOI
30-nm Tunnel FET With Improved Performance and Reduced Ambipolar Current
TL;DR: In this paper, double-gate silicon tunnel field effect transistors (TFETs) are optimized to maximize the ION current by correctly positioning the source with respect to the gate edge.
Journal ArticleDOI
Superparamagnetic Silica‐Iron Oxide Nanocomposites for Application in Hyperthermia
TL;DR: The Web of Science Record was created on 2005-01-12, modified on 2016-08-08 by as discussed by the authors, who used LTP-ARTICLE-2004-001.
Book ChapterDOI
A Framework of Product and Process Metrics for Sustainable Manufacturing
TL;DR: In this article, a framework for developing comprehensive product and process metrics for sustainable manufacturing, using machined products and machining processes examples, and addressing all three aspects of the triple bottom line -environment, economy and society.
