Special Issue Information

Dear Colleagues,

In recent decades, microelectronics and optoelectronics have received widespread attention from academics and industries and have undergone rapid development in both fundamental research and advanced applications, including high-speed information processing in electronics, sensing, display, lighting, energy harvesting, and communication. Microelectronics and optoelectronics devices are the key to future high-tech life, and their fundamental research and advanced applications are closely related. It is vital to enhance the basic research in microelectronics and optoelectronics to guide the mass production applications of integrated devices. Therefore, this Special Issue aims to present research papers, short communications, and review articles focusing on basic research on microelectronic and optoelectronic devices to reveal the underlying physics or mechanisms, as well as cutting-edge applications to present efficient electronic information processing. This research topic spans a broad variety of subjects in microelectronic and optoelectronic devices, including transistors, diodes, memristors, and their integrated devices for microelectronics, and photodetectors, light-emitting diodes, lasers, and solar cells for optoelectronics.

We look forward to receiving your submissions.

One of the primary objectives of scientific research is to create state-of-the-art multiferroic (MF) materials that exhibit interconnected properties, such as piezoelectricity, magnetoelectricity, and magnetostriction, and remain functional under normal ambient temperature conditions. In this study, we employed first-principles calculations to investigate how changing pnictogen elements affect the structural, electronic, magnetic, and optical characteristics of QFeO3 (Q = Bi, P, SB). Electronic band structures reveal that BiFeO3 is a semiconductor compound; however, PFeO3 and SbFeO3 are metallic. The studied compounds are promising for spintronics, as they exhibit excellent magnetic properties. The calculated magnetic moments decreased as we replaced Bi with SB and P in BiFeO3. A red shift in the values of ε2(ω) was evident from the presented spectra as we substituted Bi with Sb and P in BiFeO3. QFeO3 (Q = Bi, P, SB) showed the maximum absorption of incident photons in the visible region. The results obtained from calculating the optical parameters suggest that these materials have a strong potential to be used in photovoltaic applications. Full article
