Special Issue Information

Dear Colleagues,

The present Special Issue is a continuation of a previous successful Special Issue entitled “Microwave Technology and Nanomaterials: Synthesis and Application”. Our aim is to attract and report a rich variety of recent research findings on the overlapping areas of microwaves and nanomaterials.

The development and use of nanomaterials is one of the most active research areas. This class of materials has demonstrated a wide variety of applications ranging from biomedicine to sensors or energy. Nanomaterial preparation procedures are generally based on conventional heating methods with long synthetic times and reagent consumption. In addition, conventional synthesis methods sometimes lead to the formation of heterogeneous materials. By contrast, the use of microwaves as an energy source appears as a strategy that allows some or all of these inconveniences to be overcome. Further, nanomaterials are becoming an interesting tool for the development of materials able to control microwave radiation.

This Special Issue is open to any nanomaterial prepared using microwave in any synthetic steps. Materials can be 2D nanomaterials, nanoparticles, etc. Reports of applications of nanomaterials prepared following microwave assisted are welcome. Additionally, the preparation of devices containing nanomaterials designed to interact with microwaves is aligned with the topic.

Nanoporous gold (NPG) plays an important role in high-performance electronic devices, including sensors, electrocatalysis, and energy storage systems. However, the traditional fabricating methods of NPG, dealloying technique or electrochemical reduction technique, usually require complex experimental procedures and sophisticated equipment. In this work, we reported a unique and simple method to prepare the NPG through a low-temperature solution process. More importantly, the structure of the NPG-based electrode can be further controlled by using the post-treatment process, such as thermal treatment and plasma treatment. Additionally, we also demonstrate the application of the resulting NPG electrodes in flexible photodetectors, which performs a higher sensitivity than common planar photodetectors. We believe that our work opens a possibility for the nanoporous metal in future electronics that is flexible, large scale, with facile fabrication, and low cost. Full article

In this study, the efficient fabrication of nickel silicide (NiSix) Schottky barrier thin-film transistors (SB-TFTs) via microwave annealing (MWA) technology is proposed, and complementary metal-oxide-semiconductor (CMOS) inverters are implemented in a simplified process using ambipolar transistor properties. To validate the efficacy of the NiSix formation process by MWA, NiSix is also prepared via the conventional rapid thermal annealing (RTA) process. The Rs of the MWA NiSix decreases with increasing microwave power, and becomes saturated at 600 W, thus showing lower resistance than the 500 °C RTA NiSix. Further, SB-diodes formed on n-type and p-type bulk silicon are found to have optimal rectification characteristics at 600 W microwave power, and exhibit superior characteristics to the RTA SB-diodes. Evaluation of the electrical properties of NiSix SB-TFTs on excimer-laser-annealed (ELA) poly-Si substrates indicates that the MWA NiSix junction exhibits better ambipolar operation and transistor performance, along with improved stability. Furthermore, CMOS inverters, constructed using the ambipolar SB-TFTs, exhibit better voltage transfer characteristics, voltage gains, and dynamic inverting behavior by incorporating the MWA NiSix source-and-drain (S/D) junctions. Therefore, MWA is an effective process for silicide formation, and ambipolar SB-TFTs using MWA NiSix junctions provide a promising future for CMOS technology. Full article

A new method for fast and simple synthesis of crystalline TiO2 nanoparticles with photocatalytic activity was developed by carrying out a classic sol–gel reaction directly under vacuum. The use of microwaves for fast heating of the reaction medium further reduces synthesis times. When the solvent is completely removed by vacuum, the product is obtained in the form of a powder that can be easily redispersed in water to yield a stable nanoparticle suspension, exhibiting a comparable photocatalytic activity with respect to a commercial product. The present methodology can, therefore, be considered a process intensification procedure for the production of nanotitania. Full article
