A significant accomplishment of this study is the successful development of a new method that can monitor lateral variations of the local interface electric field and local interface dipoles at metal/semiconductor contacts by monitoring local variations in the electron- and hole SBHs. (2) Ion milling and inductively coupled plasma reactive ion etching (ICP-RIE) of vertical silicon nanowires, in order to increase the fraction of vertical vs. non-vertical nanowires. 2010-10-26 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1282070943 http://rave.ohiolink.edu/etdc/view?acc_num=osu1282070943 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
