This is the third MURI program grant awarded to ASU researchers in the past several years in semiconductor optoelectronics and photonics. There were more than 150 full proposals for fiscal 2010 MURI grants. Only 32 were chosen for funding.
The project in which the ASU team is involved is the only one selected this year in the area of laser and photodetector materials research.
Zhang commented, “This indicates national recognition of the research efforts at ASU in these areas. I’m very pleased to see our team selected, because competition for this particular MURI grant was very strong. Many of the teams competing are led by outstanding scientists.”
Zhang, Smith and Johnson will strive to better understand and improve the physical and structural properties of antimonide-based compound semiconductor materials. Those materials offer the potential to produce very high-performance infrared photodetectors and lasers, Johnson said.
Specifically, they’ll study superlattice systems that consist of two or more materials that are intentionally arranged in alternating semiconductor layers several nanometers thick.
The superlattice structures combined with an antimonide material system can give engineers “additional degrees of freedom when selecting for color and performance in infrared photodetectors and lasers,” Johnson commented.
The ASU team has a strong track record in this area. Zhang did pioneering work on superlattices for infrared laser applications while at the prominent Hughes Research Laboratories, and has been collaborating with Johnson and Smith on this research since he joined ASU in 1996. Smith has decades of experience studying structural properties of semiconductor superlattices.
XsunX Capitalizes on the “Darling of the Solar Industry”: CIGS
IBIS Associates says that portions of the global 70

PV market utilizing multi-crystalline silicon solar cells could achieve savings of over $646 million by replacing only 500 megawatts with XsunX CIGS by 2015.
XsunX, a developer of advanced, thin-film photovoltaic (TFPV) solar cell technologies and manufacturing processes has had favorable results from a study conducted by IBIS Associates.
The firm focused on Copper Indium Gallium (di)- Selenide, (CIGS) thin-film technology.
IBIS is a technology strategy and business development consultancy company specializing in advanced materials and manufacturing technologies. The company looked at the potential impact of XsunX’s hybrid solar technology, ‘CIGSolar’, on the global solar photovoltaic (PV) market in terms of efficiency and savings.
The study projects that portions of the Global PV market utilizing multi-crystalline silicon solar cells could achieve savings of over $646 million by replacing only 500 megawatts of multi-crystalline silicon usage with new XsunX CIGS based solar cells by 2015.
The study’s five year projection utilized XsunX’s Joint Venture licensing model under which it plans to deploy manufacturing capacity of CIGSolar which is currently under development by XsunX.
The savings were determined by utilizing the National Renewable Energy Laboratories (NREL’s) Solar Advisor Model which forecasts the savings from the projected efficiency gains of CIGSolar technology as a replacement for the use of multi- crystalline silicon cells.
“With the industry’s renewed focus on CIGS untapped potential, we believe we are positioned to reach the market at an optimal time,” said Tom Djokovich, CEO, XsunX. “It became very clear to us at the InterSolar conference in San Francisco this month that CIGS was becoming the “darling” of the solar industry, and XsunX is working to capitalize on this timing.”
The Company’s development objectives for CIGSolar, which were launched last fall, include leveraging and adapting expertise and cross- cutting technologies from the hard disk media and
