Designing of masks for quantum dot single electron transistor fabrication using E-beam nanolithography
Uda, Hashim; Sutikno, Madnasri; Zul Azhar, Zahid Jamal (Nano Science and Technology Institute, 2007)Quantum dot single electron transistor (QD SET) is able to be fabricated through a joint technique of e-beam lithography (EBL), pattern dependent oxidation (PADOX) and high density plasma etching. In this research, we have ... -
Fabrication and characterization of Si quantum dots and SiO2 tunnel barriers grown by a controlled oxidation process
Sutikno, Madnasri; Uda, Hashim; Zul Azhar, Zahid Jamal (IOP Publishing Ltd, 2008-01-29)The control of the growth of silicon dioxide (SiO2) and the formation of quantum dots (QDs) play an important role in the fabrication of single-electron transistors (SETs). In this work, SET structures were fabricated using ... -
Nano patterning of cone dots and nano constrictions of negative e-beam resist for single electron transistor fabrication
Sutikno, Madnasri; Uda, Hashim; Zul Azhar, Zahid Jamal (Springer New York, 2007-12)We present an optimization of nano dot of negative tone e-beam resist which is a very important step in single electron transistor fabrication process. The optimum design of dot and nano constriction plays a significant ... -
Nano-silver microcavity enhanced UV GaN light emitter
Naser Mahmoud, Ahmed; Zaliman, Sauli; Uda, Hashim; Zul Azhar, Zahid Jamal (Inderscience Enterprises Limited, 2009)We report results of measurements that help to clarify the role of silver in the reflection of UV emission light from GaN. A GaN as an active layer was sandwiched between two silver metal reflectors. GaN layer on sapphire ... -
A new Microelectronic Engineering degree curriculum in KUKUM
Yufridin, Wahab; Ali Yeon, Md Shakaff; Zul Azhar, Zahid Jamal; Zuraidah, Mohd Zain; Reha, Abdul Razak; Uda, Hashim (Association of Engineering Education in South East Asia and the Pacific, 2005-12-08)This paper presents the development and implementation of a new curriculum at the Kolej Universiti Kejuruteraan Utara Malaysia (KUKUM). The curriculum is specifically developed for the Bachelor of Engineering Degree program ... -
A systematic dry etching process for profile control of quantum dots and nanoconstrictions
Madnarski, Sutikno; Uda, Hashim; Zul Azhar, Zahid Jamal (Elsevier B.V., 2007-08)In essence, quantum dot dimensions and others can be laterally and vertically defined by using either bottom up or top down methods respectively. In fabrication that uses top down method, etch process hold a chief role. ...
