NEAR INFRARED SILICON-BASED PHOTODETECTOR WITH DRAMATICALLY

ENHANCED EFFICIENCY

(Document No. W90GQZ-61400034)

1. DESCRIPTION OF SERVICE.

This requirement is to provide financing in support of the research project titled “Near infrared silicon-based photodetector with dramatically enhanced efficiency” lead by Professor Jim Williams, Department of Electronic Materials Engineering, Research School of Physics and Engineering, Australian National University.

The main objective is to develop and fabricate an efficient near-infrared photodetector based on sub-band gap absorption in silicon achieved by hyper-doping with suitable impurities such as gold. A combination of ion implantation and pulsed laser melting will be used and the processing optimized to achieve impurity concentrations that exceed the solid solubility in silicon by several orders of magnitude.

This project will involve a 3-way collaboration between the Australian National University (ANU), the ARDEC Benet Labs and the University of Dayton. The approach to achieving an efficient silicon-based near-infrared photodetector derives from a proof-of-principle study by ANU, ARDEC, and co-investigators from MIT, Harvard, and RPI published in the prestigious journal Nature Communications showing a device response at wavelengths out to 2200nm from silicon (Si) hyper-doped with gold (Au). More recently, ANU, Harvard and MIT collaborators have shown that it is possible to achieve an order of magnitude higher concentration of Au in Si in a regime where the pulsed laser melting (PLM) results in a laterally non-uniform Au profile.

Despite a filamentary Au arrangement in Si, dramatically improved absorption of light in the infrared occurs and this suggests that a much more efficient photodiode than the initial device is feasible. This current project is focused on: understanding the impurity trapping and segregation processes that occur during PLM, the filamentary process at high impurity concentrations, improving the understanding to enable optimization of the optically active Au concentration (and other suitable impurities) in Si, and subsequently fabricating an optimized IR photodetector. The ANU will focus on: optimizing the ion implantation conditions and characterizing the material quality, soluble Au concentration and optical absorption before and after PLM using high resolution Rutherford backscattering (RBS), transmission electron microscopy (TEM), Raman spectroscopy and optical measurements; ARDEC will undertake and optimize the PLM processing; and UDayton will fabricate and characterize the photodetector devices. Along with other collaborators at Harvard, Albany, Illinois and Ottawa that bring further characterization and modelling/theoretical expertise to the project, ANU will attempt a full understanding of the

PLM/solidification/segregation processes and the intriguing filamentary behaviour in Si. This project will open up opportunities for exploiting hyper-doping with a range of optically active impurities in Si.

The duration of this Research and Development is 12 months with a 12-month option.
