Overview
In recent years, short-wave infrared (SWIR) technologies have gained traction in various fields, including healthcare, agriculture, security, automotive, machine vision, and virtual reality. Among the leading technologies for SWIR detection are photodetectors based on quantum-dot (QD) thin films, valued for their cost-effective, high-resolution performance and tunability to specific wavelengths. However, QDs often contain lead or other heavy metals, which pose health risks, and QD thin films are limited by low mobilities and the presence of organic ligands, which limits device response times. Developing heavy metal–free alternatives for SWIR sensors is crucial for advancing efficient, tunable, and environmentally friendly imaging technologies. We propose using black phosphorus (bP) as the active layer for this generation of devices. As a layered material, bP allows precise thickness control from monolayer to bulk, with high mobility and clean interfaces that can lead to faster device performance compared to current QD-based technologies.
Project goals
The goal of the internship / master\'s thesis project is to explore and develop black phosphorus–based thin absorbers for SWIR wavelengths and integrate them into photodetectors. Layered bP thin films will be produced via an ink process, with thickness determined by the material\'s optical properties, as the bP bandgap is tunable by the number of layers.
Responsibilities
Fabricate and characterize devices based on black phosphorus thin absorbers for SWIR photodetection.
Develop and optimize ink-based processing of layered bP films and control thickness via optical properties.
Conduct optical, structural, and electrical measurements; analyze data; iterate to improve device performance.
Work independently in a lab environment after initial training and contribute to a collaborative international research team.
Communicate findings and contribute to reports and discussions with supervisors and peers.
Qualifications and expectations
Hands-on laboratory experience and a proven record of problem-solving and data analysis.
Ability to work in an international environment; excellent knowledge of English is a prerequisite.
Interest in photodetector technology, 2D materials, and optoelectronic characterization.
