epitaxial reactor expert |
He has extensive experience, over 20 yrs, in the field of epitaxial deposition of III-V semiconductor materials for opto-electronic devices (InGaAsP/InGaAlAs/InP and AlGaAs/InGaP/GaAs based materials). This includes the growth of high-speed bipolar transitors, phototransistors, lasers, pin and avalanche high-speed photodetectors. He has operated a variety of commercial equipment including MBE systems from Vacuum Generators, Varian, and Riber and MOCVD systems from Aixtron. He has experience with many types of sources including standard effusion cells, solid and gas source crackers. In addition to these commercial systems he also has designed and built a compact gas source MBE system for the growth of InP based III-V materials. Much of his work relating to epitaxial growth has been published in peer-reviewed journals such as the Journal of Crystal Growth and Applied Physics Letters. He was one of the first researchers to develop the use of carbontetrabromide for carbon p-type doping in InGaAs materials that has been essential for the development and reliability of high-speed bipolar transistors. |

vacuum system expert
high vacuum system expert
ultra-high vacuum system expert
vacuum environment expert |
He has over 25 years of experience with vacuum systems from basic rough pumped deposition chambers to ultrahigh vacuum all metal sealed systems reaching base vacuum pressures of 1x10-11 torr. In the course of his research he has acquired extensive expertise with many types of pumping systems including Oil & Mercury Diffusion, Turbo, Ion, Cryo, Sublimation, Roots Blowers, Rotary vane, Scroll, Diaphragm, and Venturi pumps. This also includes extensive work with various vacuum measurement techniques such as Ion, Cold cathode, Manometers, Strain, Pirani, and RGA. In the course of his research he has designed, built, and operated vacuum systems for eptitaxial and thin film deposition of state of the art opto-electornic materials and high temperature, high vacuum in-situ x-ray analysis. These systems required the use of many different high temperature materials (e.g. aluminum oxide, pyrolitic boron nitride, tantulum, molybdenum, and tungsten) compatible with a high temperature and high vacuum environment. He has worked with many different vacuum deposition techniques, which include thermal (both resistive and e-beam), sputtering, PECVD, MBE, and MOCVD. He has worked with numerous systems requiring the pumping of toxic and flammable gasses such as phosphine, arsine, silane, hydrogen, oxygen, and pyrophroric metalorganics and has acquired extensive experience with all of the associated safety issues in the use of these hazardous gasses including storage, monitoring, personal protective equipment such as SCBA's, emergency response procedures, and waste removal requirements and procedures. |

X-ray diffraction analysis expert |
He has many years of experience in the field of x-ray diffraction starting from his thesis work in dynamical x-ray diffraction in fulfillment of a Master Degree from the Polytechnic Institute of New York. He has experience with numerous diffraction techniques including powder, back reflection Laue, high resolution single crystal, double crystal, dynamical and energy dispersive techniques using both sealed tube and rotating anode x-ray sources. In the course of his research he has investigated many different materials including but not limited to various thin film metal contacts, silicides, oxides, superconductors, and III-V semiconductors. He has designed and built numerous custom x-ray systems for the study of both thin film and single crystal structures. The results of these studies have been published in peer-reviewed journals such as JAP and APL. He has developed various C based software applications utilizing Fourier analysis to simulate x-ray diffraction data and extract structural parameters. |
