Point defects are atomic-scale imperfections in otherwise periodic crystals that strongly influence the electrical and optical properties of semiconductors. Once regarded as undesirable, these defects have become key building blocks of emerging quantum technologies, enabling applications in sensing, communication, and information processing.
Seminar will take place on 27 November 14:00 val. at NFTMC D401 auditorium.
In this seminar, a first-principles perspective on point defects in semiconductors will be presented. Using density functional theory, their structural, vibrational, and electronic properties are modeled to calculate electron–phonon coupling and the resulting optical lineshapes. These studies help understand the electronic and optical signatures of defect-based systems, which determine their potential applicability in quantum technologies.
All interested in quantum materials, semiconductor physics, and next-generation quantum platforms are welcome to attend.
