Facilities in Applied Physics
The research laboratories in Applied Physics are equipped with a wide range of facilities in support of surface science, superconductivity, low dimensional physics, optical interactions inside microstructures, magnetic materials, condensed matter theory, electron collision theory, medical diagnostic, and materials synthesis.
Surface Analysis and Interface Fabrication facilities include ultraviolet, x-ray and inverse photoelectron spectroscopes; Auger and electron-energy-loss spectroscopes; low-energy-electron diffraction (LEED); sputter depth profiling; work function measurement; and an oxide MBE system with electron-beam and effusion cell metal sources, and atomic and excited oxygen sources. For more information, please contact Prof. Victor E. Henrich.
Micro and nanofabrication is done in the Keck-Jones Microfabrication Facility which has a class 100 cleanroom. For more information, please contact Prof. Tso-Ping Ma.
Scanning electron microscope and microlithography equipment are in the Nanotechnology Laboratory. The Nanotechnology Laboratory has equipment for high resolution ebeam lithography, SEM characterization facilities, AFM and STM in both ambient and UHV environments, and an exceptionally wide range of device analysis capabilities. The laboratory specializes in the fabrication and investigation of nanostructured, quantum, and novel molecular scale devices. Characterization facilities include millikelvin dilution refrigerators and magnetic fields up to 12T, femto amp current resolution and SPAs. Variable temperature He-flow cryostats up to 300K complements this capability, as well as 77K direct probe capability. A 2-micron MFS adaptable HBT process (airbridge optional) with high frequency network analyzer characterization is available for device integration, high speed devices, or hybridization projects.
The laboratory is also equipped for research in MEMS, with ODE etching and thin film membrane expertise, and has full facilities of two cleanrooms for conventional MOS processes. We have facilities for chemical preparation (fume hoods, NMR, etc.) and extensive expertise in their characterization for research in molecular and biological systems, focusing on the integration with microelectronics. For more information, please contact Prof. Mark Reed.
Cryogenic facilities include an Oxford Instruments dilution refrigerator which allows study of electric transport and magneto-transport properties down to 30 milliKelvin and in fields to 11 Tesla. Relevant microwave network analyzers and sources allow ultrasensitive microwave measurements (up to 40 GHz and down to 30 mK). For more information, please contact Prof. Daniel E. Prober.
Laser Diagnostics and Optical Scattering facilities include single mode and multimode Q-switched Nd: YAG lasers (with second- and third-harmonic outputs), mode-locked and Q-switched Nd:YAG lasers (with second- and third-harmonic outputs), high repetition rate GaAs pumped Q-switched Nd:YAG lasers, an excimer-pumped narrow band dye laser, TEA N2 and CO2 lasers, and computer-controlled large pixel CCD cameras, quantum limited intensified CCD cameras, position-sensitive photomultipliers, intensified linear array photodiodes, framing cameras, and streak cameras. For more information, please contact Prof. Richard K. Chang.
Our Optics Laboratory has an infrastructure capable of high spatial and spectral resolution imaging spectroscopy from the UV (0.325 microns) to the infrared (5 microns). Imaging capability includes several traditional microscopes, a cryogenic temperature far-field microscope, and a cryogenic temperature solid immersion microscope. Two of the traditional microscopes are designed for single molecules experiments and include an epifluorescence microscope and a scanning confocal microscope. Light sources include a HeCd laser (325 microns), two 10 W Argon Ion Lasers, a tunable Ti:Sapphire Laser, and a tunable dye laser. Spectroscopic dispersion and detection equipment include several spectrometers, three Roper Scientific Grade CCDs, four EG&G single photon counting APDs, and a Mattson FTIR with an InSb detector for detection out to 5 microns. We also have a Specialty Coating Systems Spincoater for accurately spinning photoresist onto substrates and an Electronic Micro Systems precision hotplate, which allow us to prepare simple single molecule samples at Yale. For more information, please contact Prof. Robert D. Grober.
CRISP was launched in 2005 and is funded by the National Science Foundation as one of their Materials Research Science and Engineering Centers (MRSECs). It is located at Yale University and is a joint venture between Yale, Southern Connecticut State University (SCSU) and Brookhaven National Laboratory. It is an interdisciplinary effort, with faculty members from the Yale departments of Applied Physics, Chemical Engineering, Chemistry, Electrical Engineering and Mechanical Engineering, and the SCSU Department of Physics, with strong collaborations with industry and national laboratories. For more information, see the CRISP web site.
In addition to a network of various computer workstations, individual research groups maintain a variety of single and multiprocessor computers, mainly Sun, IBM, and Silicon Graphics, for computationally intensive research. The Hewlett-Packard engineering cluster also provides X Windows workstations, Unix workstations, scanners, video equipment, and printers.
