Our laboratories contain a variety of high-tech, state-of-the-art equipment for a variety of research interests. The physics department and the nanoscience department have five laboratories available for students and faculty. Some of the equipment includes
- Thin Film Deposition Equipment
The Metal Organic Chemical Vapor Deposition (MOCVD) system is available for thin film deposition on wide variety of substrates. The system was originally designed by Dr. Larry Miners. The vertical, hot wall chamber of the system is capable of utilizing four gas sources and eight liquid bubblers for deposition of multi-component compounds. The original design with improved switching of gases in the deposition chamber enables growth of abrupt junctions, since the gases can be evacuated more quickly. The entire system can be controlled automatically by means of a computer connected to a multi-programmer as well as manually.
The facility for substrate preparation equipped with an electron cyclotron resonance etcher and special chamber for chemical treatment of substrates. The JEE-4X Vacuum Evaporator is a high-vacuum specimen preparation station for evaporation of a variety of metals and other materials. It is also used in the preparation of fine-grain conductive and supportive coatings. Fitted with an turbomolecular pump, the JEE-4X, with its automatic evacuation system as standard, ensures an extremely clean, high vacuum working environment.
A home-made Electron Beam Deposition System equipped with cryo- pumped system with 10-5 Torr vacuum chamber, 20 kV power supply, Varian electron beam controller with sweep rate and amplitude control, and automatic vacuum sequencing is also available.
- Equipment for ceramic samples preparation and thermal
treatment of samples
This includes a Lindberg Muffle Furnace, Model 51848, Tmax = 1000 C with digital temperature controller, and a Lindberg Programmable Tube Furnace, single zone, Tmax = 1200 C, with tube Size 1"diameter x 24"L.
- Equipment for characterization and investigations of physical
properties of ferroelectric, magnetic and magnetoelectric materials
A QuadTech Model 1730 Precision LCR Digibridge (with measuring cell) that covers frequency interval from 100 Hz to 100 KHz in combination with two Stanford Research High Voltage power supplies that provide us with 5 kV potential difference for the application of external bias electric field to the samples during measurements.
Delta Design temperature chamber for measurements in the temperature range from – 73 to + 315 C. TekMag Aries Nuclear Magnetic Resonance (NMR) Spectrometer with 2T magnet. This spectrometer is equipped with a set of homemade probes and allows us to carry out studies of NMR and nuclear quadrupole resonance in the temperature interval from room temperature to 10K.
- Equipment for high performance computing
Our hardware capabilities include a turnkey beowulf-class supercomputer with 64 AMD Opteron processor cores, several IBM, Sun Microsystems and Linus worstations with Xeon processors, and access to the high performance computing (HPC) facilities at both the Naval Research Laboratory (NRL) and Oak Ridge National Laboratory (ORNL).
- Equipment for nanoscale spectroscopy and femtosecond lasers
See the Nano-fs laboratory website for a description of their equipment and research.
