    Optimize opto-electronic devices with new compact measuring system

    In order to develop efficient opto-electronic devices such as solar cells or LEDs, it is crucial to improve the quality of the semiconductors. To achieve this, it is necessary to determine the luminescence yield of the semiconductor material. For this characterization, a research team at HZB has developed a new measuring device that precisely determines the luminescence and is also very compact. In order to evaluate the potential for commercial applications, the team now receives a Field Study Fellowship from the Helmholtz Association. [...]
