Dr. Pooley has a background in solid-state physics and semiconductors, with 6 years experience fabricating, characterizing, and modeling semiconductor optoelectronic devices. His work has involved novel research to develop technology for quantum computing, as well as creating tools to model established consumer products such as transistors, LED lighting, photodiodes, and photovoltaic cells.
Dr. Pooley completed his Ph.D. in the Semiconductor Physics Group at the University of Cambridge, UK, in conjunction with Toshiba Research Europe Ltd. His work focused on developing components for optical quantum computing using single quantum dots embedded within semiconductor diode structures. This involved fabricating the devices in a cleanroom environment, as well as performing electrical and optical characterization measurements, before proceeding to conduct a range of novel experiments that led to 7 publications in respected journals. He has significant experience in a wide range of semiconductor fabrication methods, including: sample cleaning and preparation, wafer cleaving, photolithography, metal deposition, etching, and device bonding/packaging. He also has extensive experience in a range of spectroscopy, optical measurement, and material characterization techniques including, photoluminescence (PL), micro-PL, electro-PL, time-resolved PL, Fourier transform infrared spectroscopy (FTIR), photon correlation measurements such as HBT and HOM interferometry, atomic force microscope (AFM) imaging, and scanning tunneling microscope (STM) imaging.
In addition to his semiconductor fabrication and optical measurement skills, Dr. Pooley has a strong background in scientific programming and numerical simulation methods. He has developed systems for automatic data acquisition and processing, such as a piezo feedback system to stabilize alignment in optical measurements with long acquisition times, and analysis tools for easily extracting figures of merit from data sets using fits to mathematical models. Before joining Exponent he worked for COMSOL, where he developed the semiconductor module of their finite element simulation software.
