WAT project with a semiconductor research grant

Dr. Bartłomiej Seredyński from the Military University of Technology's Faculty of New Technologies and Chemistry has received a grant from the National Science Centre under the MINIATURA 9 competition. His project focuses on researching modern four-component semiconductors based on antimony compounds and aims to precisely determine the parameters of barrier layers in infrared detectors. The experimental study of semiconductors produced by molecular beam epitaxy is Dr. Seredyński's project, which involves evaluating a four-component material from group III and V elements of the periodic table. This research is intended to enable the precise determination of barrier layer parameters, which in modern infrared detectors determine the level of noise and dark currents. Until now, the design of barrier structures has been based on experience and trial-and-error methods, with layer configurations set approximately, without the possibility of directly measuring critical parameters. The project's goal is to introduce a systematic approach based on experimental data. "The epitaxy I use to create advanced antimony semiconductors is like building with 'atomic LEGO bricks.' However, for the structure to be durable and functional, we must know the properties of each 'brick.' My research will provide fundamental knowledge about this 'building material'—it will explain how the barrier layer behaves at the energy level. Without this data, the development of infrared detectors would be doomed to tedious and costly trial-and-error experiments," said Dr. Seredyński. Potential success of the project will lay the groundwork for further research into next-generation photonics, enabling the development of more stable, reproducible, and interference-resistant detectors suitable for the most demanding industrial and scientific applications
