For decades, electrons in semiconductors were viewed as tiny particles bouncing around, much like molecules in dilute gases. The field of electron hydrodynamics explores the fluid-like behavior of electrons, where their transport mirrors that of fluid flow. Understanding electron hydrodynamics is crucial for both fundamental research on novel materials and the development of new electronic devices.

Dr. Denis Bandurin, Assistant Professor at National University of Singapore, is focused on the comprehensive investigation of electron transport in novel quantum materials. Bandurin's work uncovered exotic hydrodynamic behavior of graphene electrons, provided the first measurements of electron viscosity in solid-state devices, and demonstrated mechanisms that govern the emergence of this regime from the free-electron state.

Bandurin's experiments have also unveiled the importance of a distinctive transport coefficient known as Hall viscosity in governing the dynamics of viscous electron transport. His findings showcased the role of the Hall viscosity in introducing corrections to the conventional Hall effect, an established phenomenon with a century-long history. He has also made significant contributions to the discovery of plasmonic Fizeau drag effect and developed novel principles of terahertz detection using graphene.

Bandurin is currently conducting unique radiation-driven magneto-transport experiments on advanced materials, aiming to unveil new fundamental phenomena in the quantum flatland while simultaneously developing practical devices for future quantum electronics. His group has been developing sensitive light detectors for infrared and terahertz frequency domains using novel quantum materials with unique electronic properties. This innovative approach facilitates robust photoresponse, which holds great significance for the future of wireless communications beyond 5G, remote sensing, and quantum communications.
