Research Overview

The ASPECT (Analysis of Semiconductor Photon-Electron Conversion Technology) lab focuses on advancing the frontiers of non-silicon semiconductors, concentrating on organic and hybrid materials to push the boundaries of photon-electron conversion mechanisms. Our research integrates fundamental material science with innovative device engineering to address current energy, imaging, and sensing challenges.

Scientific Aspects

Below are the primary research areas we explore:

• Photon–Electron Conversion: The process our lab is named after — how a photon becomes usable current in four steps, where the energy is lost along the way, and why the bandgap sets a ceiling on what a single junction can do.
• Excitons and Polarons: The quantum mechanics underneath that conversion. Why a charge in a solid is never a bare charge, and how exciton binding energy and polaron formation decide the architecture of a working device.
• Novel Semiconductors: Exploring materials that offer unique structural, optical, and electronic properties to transcend the limitations of traditional silicon-based technologies, including Organic Semiconductors and Hybrid Semiconductors, to address critical energy, imaging, and sensing challenges.
• Photodetectors: Development of sensitive, high-speed devices for light-to-electrical signal conversion. We explore novel architectures and material interfaces for next-generation imaging and sensing.

We welcome collaborations and are constantly looking for passionate researchers to join our efforts in tackling these challenges. Feel free to contact us for more information. For prospective diploma students, please fill in the Google form link before contacting us.
