Hybrid Electronics and Characterization Laboratory (HECL): Prof. Lewis, Rensselaer The HECL is the PI’s personal lab space, which is over 800 sq. ft. This laboratory houses equipment to carry out active research projects in the area of Single Molecule Conductance, Magnetotransport Properties of Hybrid Electronics and Chemical Sensors. Laboratories are located in CII 4114 and CII 4124. The HECL includes: 1) a fume hood to carry out basic and complex wet processes (i.e. sample preparations for self-assembled monolayers and porphyrin solutions) 2) a cyclic voltammetry/electrochemistry setup to determine reduction and oxidation characteristics of molecules 3) an Agilent 5500 Scanning Probe Microscope (SPM). This is a unique instrument which can perform conductance measurements (i.e., current-voltage characteristics) of nanostructures, gold nanoparticles or electronic devices. It supports a BNC breakout module for easy interface to troubleshoot or modify experiments. This system also includes an environmental isolation chamber (EIC) which gives users access to eight inlet/outlet ports to introduce gases into the sample area. In addition, the EIC provides a hermetically sealed sample compartment that is isolated from the rest of the system. This system will be used to perform in situ current-voltage measurements of the chemiresistors sensors.

This system provides ample room inside its own acoustic and vibration isolation structure to allow the user to improvise in measurement and design. This space has been used for an electromagnet purchased from GMW. 5) a 5K Closed Cycle Refrigerator with a 5T Superconducting Magnet. This system allows one to cool samples without the inconvenience and expense use of liquid helium. This instrument is capable of a multitude of measurements, including magnetotransport measurements of organic/inorganic systems. 6) a Hydrogen Flame Annealing Station is used to prepare atomically flat gold substrates for self-assembly of molecular structures Shared Facilities: 7) a Nicolet 4700FT-IR located in the Chemistry Department (Cogswell Laboratory) at Rensselaer. This system is used to perform Reflectance Absorbance Infrared Spectroscopy (RAIRS). A 500 Series Variable Angle Specular Reflectance Accessory is used to capture spectrum from thin films on gold substrates. 8) UV-VIS spectrometer located in the Optoelectronics & Optics Laboratory of Prof. Peter Persans (Physics Department). [http://www.rpi.edu/dept/phys/] 9) Center for Integrated Electronics (CIE) – CIE is a multiuser, Class 100 cleanroom facility, which has 10,000 sq. ft. of device fabrication, characterization, and metrology tools to test a variety of inorganic and organic samples. This facility is be used for photolithography and electron beam fabrication. In particular, the Carl Zeiss Supra scanning electron microscope with direct write capabilities is used to fabricate nanogap devices for molecular conductance studies. [http://www.rpi.edu/dept/cie/] 10) Center for Biotechnology and Interdisciplinary Studies - This multiuser center houses several core facilities including analytical biochemistry, which provides state-of-the-art instrumentation. In particular, the Spex FluoroLog Tau-3 Spectrofluorimenter is used to perform fluorescence measurements to verify the optical gap of the molecules.

This company provides over 550 rare and custom porphyrin and metalloporphyrin products. This company has provided iron, zinc and neutral porphyrin functionalized with thiols (-SH). [http://www.frontiersci.com/] Prof. Sang-Kee Eah (Physics Department @ Rensselaer): 12) Prof. Eah provides gold nanoparticles for chemical sensor project. [http://www.rpi.edu/dept/phys/] Prof. Christian Wetzel (Physics Department @ Rensselaer): 13) Prof. Wetzel provides Gallium Nitride samples for the chemical sensor. [http://www.rpi.edu/dept/phys/]
