Creighton University Professor Published for Work with “Fool’s Gold”

An article by Creighton University Assistant Professor of Physics and Energy Technology Andrew G. Baruth, Ph.D., article “Reactive sputter deposition of pyrite structure transition metal disculfide thing flims: Microstructure, transport and magnetism,” was published in the September 2012 Journal of Applied Physics.

Iron pyrite, commonly referred to as ‘fool’s gold’, has been identified as a strong candidate for a low-cost, earth abundant solar absorbing material for energy-related applications. In this work, a purpose-built reactive deposition chamber was developed to produce thin films of transition metal disulfides (with the pyrite structure) that were characterized optically, magnetically and electronically. The results indicate significant improvements over alternate deposition techniques and demonstrate an ability to manipulate the conduction mechanisms within the deposited material, a critical issue in next generation solar cell applications.

Baruth joined Creighton in August 2012 where he has continued his research with iron pyrite, more commonly known as fool’s gold. His research interests include developing low cost, earth abundant, sulfide-based photovoltaic thin films. Iron pyrite has been identified as a low cost earth abundant solar absorbing materail to use as energy.
