NanoMITe Annual Symposium & Nanotechnology Malaysia Annual Symposium 2019

Abstract

This Special Collection on Nanomaterials and Nanotechnology is devoted to the collection of articles from several different research fields and applications of nanotechnology which have been presented at the NanoMITe Annual Symposium and Nanotechnology Malaysia Annual Symposium (NanoSym2019) in Putrajaya during 21-22 August 2019. This Special Issue includes a selection of contributions among the papers presented at the Conference, with a peculiar emphasis on Energy, Wellness, Medical and Healthcare, Food and Agriculture and Electronics, Devices and Systems. All the published articles were peer-reviewed and selected on the base of technical novelty, scientific quality and impact in current trends of nanotechnology. Among several submissions, eleven quality papers have been selected covering the topics of nanophotonics, functional nanomaterials and application of nanotechnology in energy, biomedical and environmental fields. The purpose of publishing this special edition is twofold, firstly to promote interest in nanomaterials and nanotechnology, and secondly to convey the states of the art of the technological developments in these areas that would give a tremendous impact on the future technology, product development and on the academic society so as to encourage the increasing the research and development in nanotechnology. Here, we present a brief overview of each published article of the Special Collection and topics covered, as a guideline for the readers encouraging and stimulating the interest in reading the whole articles. Thanks to their wide direct bandgap tunability, III-nitride (III-N) compound semiconductors resulted fundamental in the development of blue light-emitting diodes that led to the so-called solid-state lighting revolution and blue laser diodes that are used for optical data storage. Beyond such conventional optoelectronic devices, 2D photonic crystal (PhC) cavities also cover an important role among the photonic devices. However, critical aspects related to their design and fabrication still need to be addressed. In this Special Collection, among the articles in the nanophotonics field, the article titled “Design of 2D GaN photonic crystal based on hole displacement for L3 cavity” by Nur Dalila Mohd Zamani et al. discusses about the 2D GaN Photonic Crystal that has the ability in controlling the propagation of light. The authors from university Kebangsaan Malaysia studied a 2D photonic crystal cavity side holes in GaN-AlN-
