NANOSCALE SOLIDS + SUPRAMOLECULAR MATERIALS

The formation of a collaborative team of SBQMI researchers from chemistry and physics has expanded the breadth of SBQMI’s materials palette and provided complementary, scalable methods to achieve atomic-scale control of materials. 

The integration of disciplines provides new approaches to facile low-temperature soft synthesis of metal oxides and related materials while maintaining the atomic-scale control over interfaces that will be essential for applications relying on strongly interacting electrons. 

The ability to shape materials from the bottom up with atomic precision holds enormous promise for manufacturability of devices for electronics, spintronics, and quantum information.  Techniques include:

  • generation of thin conformal films of mixed metal oxides, sulfides and nitrides – a solution chemistry counterpart to MBE;
  • use of adsorbed metal-organic complexes to control the electronic structure of these oxide interfaces;
  • methods for understanding and controlling organic, metal-organic and graphene-based material and interfaces on the molecular scale through surface chemistry;
  • templating techniques to intricately structure a wide range of materials in 2D and 3D.
  • The combination of these approaches has the potential to introduce new properties and functionality, transforming this area of materials research from trial and error to rational design of efficient materials and devices.
