Scanning Probe Microscopy Laboratory

Scanning Probe Microscopy Laboratory

A unique facilities extension has been completed to house the world-class Scanning Probe Microscopy Laboratory for fundamental and applied research of complex materials, particularly high Tc superconductors. The facility includes several state-of-art instrument setups, such as an UHV Variable Low Temperature (300 mK ~ 100 K) Scanning Tunneling Microscope with up to 9 T magnetic field, an UHV Ultra Low Temperature (50 mK) Scanning Tunneling Microscope, an UHV Low Temperature STM/AFM, and an UHV Low Temperature 4-probe microscope. The instrument setups are designed and constructed in-house for study of mechanical and electronic structures at the atomic level, as well as for probing physical and chemical phenomena.

Raman & Infrared Research Laboratory

Raman & Infrared Research Laboratory

The recently acquired state-of-the-art triple Raman spectrometer T64000 (Horiba Jobin Yvon) is equipped with two liquid nitrogen cooled CCDs, microscope, XYZ computer controlled stage, and software for Raman imaging. The excitation sources are Ar+ (458, 488, and 515 nm), He-Ne (633 nm), and diode (784 nm) lasers. Temperature-dependent Raman spectra can be measured under microscope between 5 and 300K using an Oxford Instruments optical cryostat and between 300 and 900K using a Linkam heating stage. The FTIR Bomem D8A spectrometer, allows infrared reflectance and transmission measurements between 10 and 24 000 cm-1 with spectral resolution of 0.03 cm-1. It is equipped with a cryostat for low-temperature studies down to 4.2 K and a set of five detectors, including liquid He cooled bolometer. Managed by Prof. Iliev

 
Ion Beam Laboratory

Ion Beam Laboratory

Includes a 2 x 1.7 MV Tandem Accelerator (RBS, ERD, NRA, Channeling, PIXE and MeV ion implantation facilities), a 30 KeV Gas cluster ion system for material modification and basic research, rapid thermal annealing system and vacuum annealing furnace, a facility on vibration and torque measurements at low temperature, flywheel, bearings, and home-made levitation devices, a 9T superconducting magnet cryostat, magneto-optic imaging and magnetron sputtering systems, laser ablation chambers, a 200 keV Ion Implanter, and a 200 keV proton beam lithographer. Managed by Prof. Chu

 
High Pressure & Low Temperature Physics Laboratory

High Pressure & Low Temperature Physics Laboratory

HTS material processing and synthesis takes place, equipped with a single crystal growth system, arc, and RF furnaces. Bulk materials are prepared in hot isostatic presses (200Mpa @ 1200 °C), thin film growth capabilities include DC and RF sputtering, thermal evaporation, laser ablation, and co-evaporation systems. The lab includes a 100 PSI jet mill for sub-micron particles and a continuous wire plastic extrusion apparatus. Managed by Dr. Chu
