Special Issue Information

Dear Colleagues,

Scientists all over the world actively want to discover new advanced materials in electrical and mechanical engineering. In recent years, applications of advanced materials have increased in the areas of semiconductor and electronic device technology, design, manufacturing, physics, and modeling. Therefore, the fields of electrical and mechanical materials have been subjects of review. They not only encompass material sizes at the nanoscale, but also in various dimensions where the onset of size dependent phenomena usually enables novel applications. This Special Issue "Advanced Materials on Electrical and Mechanical Application" covers the following scopes: fundamental and advanced materials of electrical and mechanical engineering; their synthesis and engineering; their application on optical sensors, magnetic, acoustic, and thermal transduction; their integration with many elements; the design of electrical or mechanical devices; the evaluation of various performances; and the exploration of their broad applications in industry, environmental control, material analysis, etc. We invite investigators to contribute original research articles, as well as review articles, to this Special Issue.

In addition, “The 2nd IEEE International Conference on Knowledge Innovation and Invention 2019” (IEEE ICKII 2019) which is organized by our institution will be held in Seoul, South Korea on 12–15 July 2019. The authors of the papers that will be presented at IEEE ICKII 2019 about the topics are invited to submit their extended versions to this Special Issue after the conference. Submitted papers should be extended to the size of regular research or review articles, with at least a 50% extension of new results.

The potential topics include, but are not limited to, the following:

  • Developments of advanced materials for new electrical and optical properties;
  • Nanomaterials for preparation and applications;
  • Combinatorial methods of advanced materials for mechanical design and optimization;
  • Advanced materials for preparation and applications;
  • Subjects related to electronic thin films and coating technology;
  • Synthesis engineering of advanced materials;
  • Advanced materials in mechatronics.

Schedule:

Manuscript Due: 30 November 2019
First Round of Reviews: 31 December 2019
Second Round of Reviews: 31 January 2020
Acceptance of Final papers and Publication: 31 March 2020

Using the first-principle calculation that is based on the density functional theory (DFT), our group gains some insights of the structural, electronic and optical properties of two brand new types of BiOI/TiO2 heterojunctions: 1I-terminated BiOI {001} surface/TiO2 (1I-BiOI/TiO2) and BiO-terminated BiOI {001} surface/TiO2 (BiO-BiOI/TiO2). The calculation illustrates that BiOI/TiO2 heterojunction has excellent mechanical stability, and it shows that there is a great possibility for the BiOI/TiO2 heterojunction to be used in visible-light range, hence the photocatalytic ability can be enhanced dramatically. Especially, from the calculation, we discovered that there are two specific properties: the band-gap of 1I-BiOI/TiO2 heterojunction reduces to 0.28 eV, and the BiO-BiOI/TiO2 semiconductor material changes to n-type. The calculated band offset (BOs) for 1I-BiOI/TiO2 heterojunction indicates that the interfacial structure contributes a lot to a suitable band alignment which can disperse the photo-generated carriers into the opposite sides of the interface, so this could effectively weaken the electron-hole recombination. Meanwhile, the built-in potential around the interface accelerates the movement of the photo-generated electron-hole pairs. We believe this is the reason that the BiOI/TiO2 material shows perfect photocatalytic performance. This paper can provide theoretical support for the related research, especially the further research of the BiOI-based material. Full article

The silicon-on-insulator (SOI) metal-oxide-semiconductor field-effect transistors (MOSFETs) suffer intensive self-heating effects due to the reduced thermal conductivity of the silicon layer while the feature sizes of devices scale down to the nanometer regime. In this work, analytical models of thermal conductivity considering the self-heating effect (SHE) in ultra-thin body fully depleted (UTB-FD) SOI MOSFETs are presented to investigate the influences of impurity, free and bound electrons, and boundary reflection effects on heat diffusion mechanisms. The thermal conductivities of thin silicon films with different parameters, including temperature, depth, thickness and doping concentration, are discussed in detail. The results show that the thermal dissipation associated with the impurity, the free and bound electrons, and especially the boundary reflection effects varying with position due to phonon scattering, greatly suppressed the heat loss ability of the nanoscale ultra-thin silicon film. The predictive power of the thermal conductivity model is enhanced for devices with sub-10-nm thickness and a heavily doped silicon layer while considering the boundary scattering contribution. The absence of the impurity, the electron or the boundary scattering leads to the unreliability in the model prediction with a small coefficient of determination. Full article
