Quantum Materials

Why Quantum Materials?

We are on the brink of a technological revolution that will shift data processing and usage, from the individual scale to the ‘grid’ scale. Yes, with the advent of cloud storage and in-database processing, you’re going to start hearing experts talk about the ‘data grid’ much like infrastructure experts talk about our power grid.

What Quantum Materials?

  1. Topological states of matter – MBE grown and CVD grown: PbSnTe, PbSnSe, Bi-based
  2. 2D materials
  3. Heterostructures

Methods

Our method consists in a hybrid approach that combines material synthesis using MBE and CVD with electrical and optical characterization techniques. It allows us to produce, measure and identify materials with specific electronic and optical properties that can be integrated into functional devices. A list of the synthesis and characterization techniques used in our lab is given below:

  1. Molecular beam epitaxy (with the MBE group at Notre Dame)
  2. Chemical vapor deposition
  3. Infrared magnetooptical spectroscopy
  4. Magnetotransport
  5. Strong magnetic fields
