Area-selective ZnO thin film deposition on variable microgap electrodes and their impact on UV sensing
Qazi Muhammad, Humayun; Muhammad Kashif, Muhammad Faroow; Uda, Hashim, Prof. Dr. (Hindawi Publishing Corporation, 2013)ZnO thin films were deposited on patterned gold electrodes using the sol-gel spin coating technique. Conventional photolithography process was used to obtain the variable microgaps of 30 and 43 μm in butterfly topology by ... -
Selective growth of ZnO nanorods on microgap electrodes and their applications in UV sensors
Qazi Muhammad, Humayun; Muhammad Kashif, Muhammad Faroow; Uda, Hashim, Prof. Dr.; Ahsanulhaq, Qurashi (Springer, 2014-01)Selective area growth of ZnO nanorods is accomplished on microgap electrodes (spacing of 6μm) by using a facile wet chemical etching process. The growth of ZnO nanorods on a selected area of microgap electrode is carried ... -
Structural, Optical, Electrical, and Photoresponse Properties of Postannealed Sn-Doped ZnO Nanorods
Qazi, Muhammad Humayun; Muhammad Khasif; Uda, Hashim (Hindawi Limited, 2013)Tin (Sn) doped ZnO nanorods were synthesized on glass substrate using a sol-gel method. The synthesized nanorods were postannealed at 150, 350, and 500∘ C. The surface morphologies of Sn-doped ZnO nanorods at different ... -
ZnO thin film deposition on butterfly shaped electrodes for ultravioletsensing applications
Qazi Muhammad, Humayun; Muhammad Kashif, Muhammad Faroow; Uda, Hashim, Prof. Dr. (Elsevier GmbH, 2013-12)ZnO thin film was deposited on patterned gold electrodes using sol-gel spin coating technique. Conven-tional photo-lithography with wet etching process was used to create butterfly shaped 13-m gap fromzero gap chrome mask. ...
