研究领域

Prof. Karl Leo is an internationally recognized researcher in condensed matter physics. Among his achievements are the first observations of coherent electronic dynamics in solids (quantum beats and Bloch oscillations in semiconductor superlattices) and pioneering work on organic semiconductors, including the successful introduction of controlling doping in organic components; electronic components with world record efficiency (OLED, organic solar cells) and maximum frequency (organic transistors), and the first realisation of organic inversion transistors. Many of these technologies were successfully transferred to spin-off companies like Novaled and Heliatek.
