Grow Contaminant-Free Carbon Nano/Microstructures at Low-Temperature

  • Growth technique for creating carbon features of controllable dimensions
  • Uses a low-cost and readily accessible photocatalyst and laser to grow carbon nano- and microstructures at low temperature
  • Can produce custom patterns, including arrays of structures with pitch below 100 micrometers

Abstract

The University of Central Florida invention describes methods of patterning well-defined nanoscale and microscale carbon structures with light using a defect-engineered photocatalyst. This invention avoids several shortcomings of current methods of carbon structure growth, such as external heating and residual contamination in the final products.

Partnering Opportunity

The research team is seeking partners for licensing and/or research collaboration.

Stage of Development

Prototype available.

Advantages

  • Uses a non-noble metal catalyst obtained by introducing defects in a fairly abundant material
  • Produces carbon features with no chemical or metallic contaminants and features can be tuned from a few nanometers to several millimeters in diameter and length
  • Takes seconds to grow structures
  • Growth process can be tuned at different wavelengths in the visible range, making it possible to design processes that take advantage of various lasers or solar illumination

Potential Applications

  • Interconnects for (nano)electronics
  • Microelectrodes for 3D sensor systems used in biotechnology
  • Electrodes for batteries and supercapacitors
  • Emitters for LED-type applications and emitters for sensing
  • Solar cells, sensors, devices such as diodes and transistors
