With the SFPV technology, a carefully designed partially screening top electrode lets the gate electric field sufficiently penetrate the electrode and more uniformly modulate the semiconductor carrier concentration and type to induce a p-n junction. This enables the creation of high quality p-n junctions in semiconductors that are difficult if not impossible to dope by conventional chemical methods.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>\u201cIt\u2019s time we put bad materials to good use,\u201d says physicist Alex Zettl, who led the research along with colleague Feng Wang. \u201cOur technology allows us to sidestep the difficulty in chemically tailoring many earth abundant, non-toxic semiconductors and instead &hellip; <a href=\"http:\/\/bucktownbell.com\/?p=5267\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[737],"tags":[730,100],"class_list":["post-5267","post","type-post","status-publish","format-standard","hentry","category-stem","tag-berkeley","tag-interesting-research"],"_links":{"self":[{"href":"http:\/\/bucktownbell.com\/index.php?rest_route=\/wp\/v2\/posts\/5267","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/bucktownbell.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/bucktownbell.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/bucktownbell.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/bucktownbell.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=5267"}],"version-history":[{"count":3,"href":"http:\/\/bucktownbell.com\/index.php?rest_route=\/wp\/v2\/posts\/5267\/revisions"}],"predecessor-version":[{"id":5478,"href":"http:\/\/bucktownbell.com\/index.php?rest_route=\/wp\/v2\/posts\/5267\/revisions\/5478"}],"wp:attachment":[{"href":"http:\/\/bucktownbell.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=5267"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/bucktownbell.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=5267"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/bucktownbell.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=5267"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
