About Us

The Interface and Surface Characterization Laboratory (ISC) at King Mongkut’s University of Technology Thonburi (KMUTT), part of the Nanoscience and Nanotechnology Graduate Program, focuses on perovskite-based optoelectronic technologies. Our research centers on the development of advanced perovskite materials and device architectures for solar cells and photodetectors, with the goal of improving both device efficiency and long-term operational stability. The laboratory integrates cutting-edge fabrication methods, including atomic layer deposition (ALD), low-temperature thermal evaporation, sputtering, and electron-beam deposition, together with precise surface and interface engineering strategies. Devices are fabricated and evaluated under carefully controlled conditions to ensure high reproducibility, reliability, and measurement accuracy.

A key strength of the ISC laboratory is its strong emphasis on interface and surface characterization. Through collaboration with the Synchrotron Light Research Institute (SLRI), Thailand, we utilize advanced synchrotron-based techniques such as X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy (UPS), low-energy electron microscopy (LEEM), and photoemission electron microscopy (PEEM) to investigate surface chemistry, work-function variation, electronic structure, and interfacial energy alignment in perovskite devices. By combining advanced device fabrication with in-depth surface and interface analysis, the ISC laboratory aims to deliver innovations that unite high performance, interfacial stability, and device reliability, contributing to sustainable progress in next-generation optoelectronic technologies.
