Gerardo Morell of the Institute for Functional Nanomaterials at the University of Puerto Rico has developed an economical method for producing microcrystalline diamond films.

This new approach, which uses an inexpensive source of carbon, is a significant step for carbon-based electronics. The integration of diamond into high-powered and high-temperature electronic devices could improve their performance.

The performance of high-powered and high-temperature electronics can degrade as heat builds up in the devices. By incorporating diamond, with its superior heat-removal properties, into such devices, researchers can extend their working lifetimes.

The research, conducted in collaboration with James Scott of Cambridge University, England, uses plastic food-wrap (polythene) as the source of carbon for diamond seeding and special chemical vapor reaction conditions to form thin diamond films. A patent application was filed for this process of diamond film production.
