Shaping the Future: Contributions of Layered Semiconductors and High-k Oxides for Advanced Nanoelectronics, Photonics, and Energy Technologies
Please describe the research you are conducting at R-GIRO.
At R-GIRO, I am conducting research on layered semiconductors and high dielectric constant (κ) dielectric materials to drive next-generation electronic, photonic, and energy-harvesting devices with a strong emphasis on zero-carbon neutrality. My work comprises the development of atomically thin 2D semiconductors MX₂ (M = Mo, W; X = S, Se) and high-κ dielectrics (e.g., AlOx, TiO₂, ZrO₂, AlTiO, HfO₂) using simple and energy-efficient methods and their subsequent integration for the fabrication of advanced electronic and photonic devices including transistors, UV photodetectors, photocatalytic and solar cells. By combining experimental material growth and device fabrication with advanced simulations, I aim to achieve low-power, high-performance, and eco-friendly technologies that can significantly advance energy-efficient nanoelectronics and sustainable energy devices while contributing to zero-carbon neutrality.

What is interesting about your research?
What excites me most in my research is the ability to engineer materials at the atomic scale to unlock exceptional electronic and photonic performance in real-world devices, including transistors, solar cells, photocatalytic and neuromorphic computing systems. I am particularly motivated by the design of hybrid materials through eco-friendly, scalable methods such as atmospheric mist chemical vapor deposition. Mist CVD offers an eco-friendly, low-cost alternative to conventional ALD, Sputtering, and CVD by using solution-based precursors at atmospheric pressure, enabling precise composition control, large growth rate, lower growth temperatures, and scalability. The technique allows synergistic integration of their properties into high-performance devices. My work bridges fundamental materials science with practical applications, contributing to sustainable, energy-efficient technologies and driving progress in next-generation electronics and photonics, that ultimately motivate me to continue pushing the boundaries of the respective research field.

What do you think about advancing research through interdisciplinary collaboration?
I strongly believe that advancing research requires interdisciplinary collaboration. Today’s challenges in energy, electronics, and sustainability are far too complex to be solved within a single discipline. By integrating expertise from materials science, physics, chemistry, engineering, and data science, we can design more innovative solutions and develop practical technologies. In my own work, collaborations have been crucial in bridging fundamental materials growth with device fabrication and evaluation. I actively engage with over a dozen research groups across Japan, Bangladesh, Malaysia, Saudi Arabia, and the USA. Maintaining such a global network through the combination of theoretical, experimental, and statistical expertise has resulted in impactful contributions and high-quality publications. Recently, a collaborative effort of Japan-Bangladesh-Malaysia teams has unveiled a low-temperature, eco-friendly process for extracting silicon and silica from river sand. This research not only advances sustainable material utilization but also offers an effective adsorbent for industrial dye removal, demonstrating how global collaboration can generate real societal impact. Further research on its applications in electronic and photonic devices, including photodetectors, solar cells, and photocatalytic and energy storage devices, is indeed ongoing while retaining strong collaboration.

In addition to my core research, I am passionate about fostering international collaboration, nurturing young researchers, and contributing to the academic and professional community through scholarly volunteer service. This includes serving on editorial boards of prestigious publisher; Institute of Physics IOP, Springer Nature, and Frontiers, and reviewing hundreds of publications in top-tier journals, and providing research-related support, all of which ultimately lead to engagement with the scientific community. Moving forward, I aim to bridge fundamental research with practical applications that advance sustainable development and zero-carbon neutrality, while strengthening global partnerships to maximize both scientific and societal impacts.
