Laser Spectroscopy and Chemical Physics - Postdoctoral Position

Laser Spectroscopy and Chemical Physics
    A postdoctoral position, from 1 up to 3 years duration, is available starting summer/fall of 2017 in the laboratory of Dr. Tony Smith at Ideal Vacuum located in Albuquerque, New Mexico. The research involves laser spectroscopic studies of reactive intermediates of the carbon family, group 14 containing elements (C, Si, Ge, Sn, and Pb) with particular emphasis on those that are of importance to vacuum coating and deposition processes, such applications as, thin film coating, chemical vapor deposition, semiconductor growth, and astrophysics. These transient species are produced in the gas-phase either by laser ablation or electric discharge and are studied inside free-jet expansions. Laser-induced fluorescence (LIF), stimulated emission pumping (SEP), dispersed fluorescence (DF), and fluorescence lifetimes are used to detect and characterize these reactive intermediate molecules. We also use ab initio quantum chemistry methods to predict molecular structures and spectroscopic parameters to aid our experimental data analysis. Personnel in the laboratory have the opportunity to conduct experiments with the instrumentation at Ideal Vacuum and travel to do collaborative research with other research groups.
    We are seeking research scientists that excel at collecting experimental data. Hands on skills operating and manual tuning of commercial lasers is a must. In our laboratory, we have the following laser and high technology research equipment:
    Key Laboratory Equipment
    • Coherent 699-21 Ultra-High Resolution Ring Dye Laser
    • Coherent 899-21 Ultra-High Resolution Ti:Sapphire Laser
    • CW Ring Laser Dye Pulse-Amplifier (Resolution 200 MHz)
    • Coherent Verdi CW Pump Laser
    • Lumonics HD-500 Low-Resolution Pulse Dye Lasers (Resolution 0.08 cm-1)
    • Continuum Surelite SL-III Nd:YAG Lasers
    • Lambda Physik Scanmate 2E (Resolution 0.03 cm-1)
    • Spex 500M Scanning Monochromator
    • Andor iStar 320T intensified CCD camera
    • Thermo Nicolet iS50 FT-IR Spectrometer (Precursor Gas Quality Analysis)
    A qualified candidate will have experience operating, setting up experiments, and hands-on tuning/alignment of these types of laser systems. For example, we collect Ultra-high resolution (UHR) spectra with a 300 MHz Doppler limited linewidth using our cw ring laser pulse dye amplifier apparatus. Our UHR LIF spectra are calibrated by simultaneously collecting the sub-Doppler spectrum of I2 and fringes from both a 1.5 GHz and 300 MHz etalons (etalons are passively-locked to a stabilized He:Ne laser beam while also being temperature and pressure stabilized) allowing calibration to 10 MHz. A good candidate will be efficient at operating these types of complicated experimental setups and excel at collecting spectroscopic data.
    We use commercially precursors when available, for example, (CH3)3SiCF3, Si(CH3)4, Sn(CH3)4, and many others. We also synthesis custom precursors to target high concentration production of a selected intermediate inside our pulsed jet source expansion. For example, we have recently synthesized stannane (SnH4) and stannane-d4 (SnD4) by the in vacuum reaction of SnCl4 with LiAlH4 or LiAlD4. We use gas-phase FTIR to characterize our reaction products and to gauge the purity of our precursor samples.
    Ideal Vacuum operates a full CNC machine shop and we are constantly designing new components to improve the capabilities of our spectroscopy laboratory apparatus. We seek candidates that have experience designing equipment in Solidworks 3D CAD software package. We are constantly upgrading our discharge electronics and building other small electronical circuits for our laboratory. Candidates that have some experience designing laboratory test circuits is desired.

Applied Vacuum Technology
    Ideal Vacuum is a New Mexico based distributor of scientific and industrial vacuum equipment with pumping technologies, such as, rotary vane, dry scroll, turbomolecular, and others along with vacuum pressure measurement, fittings, hardware, and supplies since 2001. The majority of our 6,000 current products either directly produce, measure, or contain vacuum. We want to extend our product range into applied vacuum process applications, such as, sputtering, thermal evaporation, electron beam evaporation, and ion beam sources to produce controlled growth of thin films for industrial production and chemical engineering process applications. Thin films are used in many industrial manufacturing processes, for example, displays, tool coating, photovoltaics, medical, optical, lighting, automotive, wear coating and others. The deposited material produces physical and chemical changes in a base material, for example, thin films layers of lanthanide containing materials can be used to produce catalytic reactions for organic synthesis. We need a qualified and committed individual with a knowledge of applied vacuum deposition techniques to bring experience and guidance as a member of our thin film deposition source technical product integration and development committee.


Thin Film Deposition Methods
    Magnetron Sputtering Cathodes
  • Virtually Any Target Material Deposition
  • RF, DC, & Pulsed DC Power Driven
  • High Vacuum & Ultra High Vacuum Applications
    Inverted Magnetrons
  • Cylindrical Targets Surround the Substrate With Coating Material
  • DC, Pulsed DC, or AC Power Driven
  • Conformal 3D Coatings, Eliminates Substrate Rotation

    Thermal Evaporation Sources
  • Resistive Element Heated Thermal Evaporation
  • Filaments, Boats, Boxes, & Rods Sources
  • Point Source Evaporation (Organic Materials)

Technical Product Integration
    Our technical scientists and application support engineers assist our graphics & product marketing department by preparing technical manuscripts for these product web page listings. This positions will require excellent English writing skills, the ability to read and comprehend technical vacuum products manuals, datasheets, and catalogs. To prepare a selected technical product manuscript we often have to read, study, and review published literature about those selected types of products and then condense that information into a concise and well-advertised product listing.
