Prof. Saif Islam Recieves DURIP Award

The DARPA Award is worth $800,000 for Research on Quantum Advanced Detectors and Energy Conversion Devices.

Prof. Islam has recently been awarded a grant from the Defense Advanced Research Projects Agency (DARPA) to work on sensors based on semiconductor pillar arrays for an ultra broadband (0.5 to 5µm) highly sensitive focal plane array that will operate at 200K. The objective of the Photon-Trap Structures for Quantum Advanced Detectors (PT-SQUAD) program is to develop a semiconductor pillared architecture that will significantly increase photon trapping and their subsequent absorption and generation of electron-hole pairs. The ultimate goal of the program is to develop a 1024 x 1024 infrared camera with a high detectivity (>1 x 1011cm√Hz/W) and low noise equivalent temperature (≤ 50mK) at 200K using semiconductor pillars. The innovative concept of semiconductor pillar based photon-trapping allows complete absorption of photons in opto-electronic devices without the use of anti-reflection coating, which is a very attractive characteristic for energy harvesting devices such as solar cells. In April 2009, UC Davis filed for a patent on semiconductor pillar based photonic devices that was co-invented by Prof. Islam and two of his graduate students: Logeeswaran Veerayah Jayaraman and Aaron Katzenmeyer. The DARPA team consists of UC Davis, UCLA, MIT, HRL Laboratories and DRS Sensors & Targeting Systems. In last one year, DoD has awarded more than 1 Million dollars to Prof. Islam’s group including an equipment grant, a seedling grant and the PT-SQUAD program.
