Prof. Dr. Colombo Bolognesi is a leading researcher in semiconductor devices and mm-wave transistors at ETH Zurich. His work focuses on the development of high-performance heterostructure field-effect transistors (HEMTs) and heterojunction bipolar transistors (HBTs) for millimeter-wave applications. His research explores advanced materials such as GaAsSb, InAs/AlSb, and AlInN/GaN for high-frequency and high-power devices. He has published extensively on topics including transistor modeling, interface roughness scattering, and charge control in quantum wells. His contributions have led to significant advancements in high-electron-mobility transistors (HEMTs) with high cutoff frequencies and output power, making them suitable for THz and millimeter-wave communication systems.
