We study the physics of quantum and topological materials using Scanning Tunneling Microscopy & Spectroscopy and other experimental techniques. We explore their basic physics and their quantum technology application in optoelectronics, spintronics and valleytronics. We investigate their implementation in silicon photonics integrated devices. Our experiments include photoluminescence, elastic/inelastic light scattering and local/non-local electrical transport in quantizing magnetic fields. We do ourselves the experiments in the extreme quantum limit at temperatures down to 20 milliKelvin, static magnetic fields up to 45 Tesla, pulsed up to 100 Tesla and under infrared/Terahertz radiation from free electron lasers; for these experiments we use instrumentation at international research infrastructures.
