Description

Quantum phenomena are currently at the forefront of scientific inquiry, offering insights into exotic electronic phases within matter. My research focuses on unlocking the mysteries of these phases in atomically thin Van der Waals materials. Through an innovative electrostatic doping technique called space charge doping, we have developed a method that safeguards the sample's surface while introducing significant electron or hole doping, ultimately triggering remarkable electronic phases.
Our investigation employs a scanning tunnelling microscope in conjunction with space charge doping, enabling us to scrutinize the atomic-level electronic response to doping in these materials. This research could provide valuable insights into the driving forces behind quantum phases, such as superconductivity and charge density waves.
