LETs can potentially offer advantages over FETs in switching speed and switching energy. Furthermore, LETs provide unique functions that not available from FETs, for instance, multiple-beam gating, which allows for the realization of <em>OR<\/em> and <em>AND<\/em> logic function with a single LET, in turn, new and simplified circuit designs. This project will use LETs to construct an XOR gate that is the key component of a half adder or full adder in computing applications.<\/p>\n<div id=\"attachment_415\" style=\"width: 501px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/pages.charlotte.edu\/nanosure\/wp-content\/uploads\/sites\/244\/2018\/12\/Zhang-2020.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-415\" class=\" wp-image-415\" src=\"http:\/\/pages.charlotte.edu\/nanosure\/wp-content\/uploads\/sites\/244\/2018\/12\/Zhang-2020-300x88.jpg\" alt=\"\" width=\"491\" height=\"144\" srcset=\"https:\/\/pages.charlotte.edu\/nanosure\/wp-content\/uploads\/sites\/244\/2018\/12\/Zhang-2020-300x88.jpg 300w, https:\/\/pages.charlotte.edu\/nanosure\/wp-content\/uploads\/sites\/244\/2018\/12\/Zhang-2020-1024x301.jpg 1024w, https:\/\/pages.charlotte.edu\/nanosure\/wp-content\/uploads\/sites\/244\/2018\/12\/Zhang-2020-768x225.jpg 768w, https:\/\/pages.charlotte.edu\/nanosure\/wp-content\/uploads\/sites\/244\/2018\/12\/Zhang-2020.jpg 1506w\" sizes=\"auto, (max-width: 491px) 100vw, 491px\" \/><\/a><p id=\"caption-attachment-415\" class=\"wp-caption-text\">Fig.1 Schematic of LET, NOR and NAND gate constructed with LETs<\/p><\/div>\n<h3><strong><span style=\"text-decoration: underline\">REU Students\u2019 Role<\/span><\/strong><\/h3>\n<p>The student will help the circuit design and implement the design using discrete components to construct and characterize the circuit, and to demonstrate the intended functions.
