In this work, the dependency of the TCF on the free charge carriers in silicon has been identified and extensively studied for the first time. A TCF compensation technique has been successfully demonstrated by depleting the charge carriers through the creation of pn-junctions in the body of the resonator. \u003C\/p\u003E\n\u003Cp\u003EThis novel idea also re-introduces single-crystal-silicon as a highly temperature-stable platform for high precision resonant sensors, including chemical, inertial, and temperature sensors. It further encourages research to extend the silicon platform for coupled-resonator tunable-filters and resonator-based mixers that are touted as primary requirements for the future of wireless communications, including cognitive radios. \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"ECE graduate research assistant Ashwin Samarao won the Best Student Paper Award at the 2010 IEEE International Frequency Control Symposium, held in Newport Beach, Calif. from June 2-4.","format":"limited_html"}],"field_summary_sentence":[{"value":"Ashwin Samaro wins Best Student Paper honors."}],"uid":"27241","created_gmt":"2010-06-28 00:00:00","changed_gmt":"2016-10-08 03:08:15","author":"Jackie Nemeth","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2010-06-28T00:00:00-04:00","iso_date":"2010-06-28T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"64606":{"id":"64606","type":"image","title":"photo of Ashwin Samarao","body":null,"created":"1449176753","gmt_created":"2015-12-03 21:05:53","changed":"1475894569","gmt_changed":"2016-10-08 02:42:49","alt":"photo of Ashwin Samarao","file":{"fid":"192044","name":"tdg59392.jpg","image_path":"\/sites\/default\/files\/images\/tdg59392_0.jpg","image_full_path":"http:\/\/tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/tdg59392_0.jpg","mime":"image\/jpeg","size":14217,"path_740":"http:\/\/tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/tdg59392_0.jpg?itok=XoVpMOSC"}}},"media_ids":["64606"],"related_links":[{"url":"http:\/\/www.gatech.edu\/","title":"Georgia Tech"},{"url":"http:\/\/www.ece.gatech.edu\/","title":"School of Electrical and Computer Engineering"},{"url":"http:\/\/www.ece.gatech.edu\/research\/integrated-mems\/","title":"Integrated MEMS Laboratory"},{"url":"http:\/\/www.ieee-uffc.org\/frequency_control\/symposia\/2010fcs\/","title":"2010 IEEE International Frequency Control Symposium"}],"groups":[{"id":"1255","name":"School of Electrical and Computer Engineering"}],"categories":[{"id":"129","name":"Institute and Campus"},{"id":"134","name":"Student and Faculty"},{"id":"143","name":"Digital Media and Entertainment"},{"id":"145","name":"Engineering"},{"id":"149","name":"Nanotechnology and Nanoscience"},{"id":"135","name":"Research"},{"id":"150","name":"Physics and Physical Sciences"}],"keywords":[{"id":"12105","name":"Ashwin Samarao"},{"id":"12106","name":"Farrokh Ayazi"},{"id":"109","name":"Georgia Tech"},{"id":"12107","name":"Integrated MEMS Laboratory"},{"id":"166855","name":"School of Electrical and Computer Engineering"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EJackie Nemeth\u003C\/strong\u003E\u003Cbr \/\u003ESchool of Electrical and Computer Engineering\u003Cbr \/\u003E\u003Ca href=\u0022mailto:jackie.nemeth@ece.gatech.edu\u0022\u003EContact Jackie Nemeth\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2906\u003C\/strong\u003E","format":"limited_html"}],"email":["jackie.nemeth@ece.gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
