Controlled synthesis of nanostructures and thin films by CVD and PLD using real-time diagnostics, including 2D layered materials (metal chalcogenides, graphene), carbon nanostructures (nanotubes, nanohorns), oxide thin films and heterostructures with atomically-engineered interfaces, as well as hybrid organic/inorganic perovskite films. Wet/dry assembly of these materials into optoelectronic device architectures (photovoltaic, photocatalytic, ultrafast spectroscopy, environmental testing) over multiple length scales.

- Oxide Target Synthesis
- Standard facilities for milling, drying, pressing, and sintering of oxide materials, to prepare PLD targets.
- Sonospray deposition of nanomaterials and organics
- Computer-controlled sono-spray deposition of nano materials, polymers, and nano composites from solutions and suspensions for uniform or patterned deposition on small or large areas (up to 1ft x 1ft) with minimum feature size of 1.5 mm. The system enables multilayer deposition on various substrates, including polymers, while controlling the substrate temperature (up to 180C). A micro-syringe pump feeds a solution allowing deposition from small (<10ml) volumes of solution and a dual-syringe configuration allows simultaneous deposition from two different solutions with variable ratio. The system is also equipped with a sono-syringe, to prevent precipitation of material during deposition (min required volume 20ml).
- Hybrid Organic/Inorganic Perovskite Films and Device Fabrication
- Formed by solution phase synthesis techniques and spin coating or Sonospray deposition. Associated layer by layer deposition, processing, and electrode application.
- 2D Crystal Stamping
- A microscope based setup to transfer exfoliated or CVD-grown layers of 2D materials from polymer-coated ribbons is available, allowing the stamp-fabrication of 2D heterostructures.
