Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adom201300406-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Light‐emitting devices based on Mg_xZn_1‐xO/ZnO:RE/Si heterostructures</bold> are proposed. Hot holes formed in Mg_xZn_1‐xO layers enter into ZnO:RE layers to impact‐excite the RE³⁺ ions therein. From the devices using ZnO:RE (Eu, Er and Tm) films, electroluminescence in red, green, blue, and also optical‐communication wavelengths are achieved. Such RE‐related electroluminescence can be activated by extraordinarily low voltages of only several volts. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4mw63339" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
