Scanning Tunneling Microscope

 

Low temperature STM provides spatial and energy resolution at the atomic scale reliably at a variable temperature down to 2K with a magnetic field up to 8T under ultra-high vacuum condition. The preparation chamber equipped with a sample heating stage and a sputter ion gun enables us to prepare an atomically clean surface. The system is also customized to adopt RHEED system and multiple thermal deposition sources for the future applications.

Temperature Controlled Microscope Stage

 

Linkam Temperature Controlled Microscope stage enables microscope imaging for samples in the temperature range -196° to 600°C, in both reflection and transimission mode.

Photonic Science Laue camera

 

Photonic Science digital Laue X-ray camera upgrades the existing X-ray source of the X'pert3 diffractometer to allow crystal orientation with accuracy down to 0.5 degree, with a 6-axis motorized sample stage.

Powder X-ray Diffractometer

 

Panalytical X'Pert3 Diffractometer features high resolution goniometer for powder x-ray diffraction and reflectivity for thin films,

Low-Temperature Atomic Force Microscope

 

from Attocube (Feb, 2013 ) has been installed, capable of AFM, PFM, MFM, cAFM at low temperature and high-vaccum 

Quantum Design PPMS

 

a unique laboratory equipment which is optimized to perform a variety of automated measurements such as Heat capacity, Thermal conductivity, Magnetization, Dielectric constant and Resistivity.

Quantum Design MPMS

 

used for performing the fundamental study of magnetism in research application of physics. MPMS sample magnetometers employ SQUID ( Superconducting  QUantum Interference Device ) technology to achieve superior measurement sensitivity, dynamic range, and reproducibility

Carl Zeiss Axio Imager

Fully motorized microscope with polarized light, sitting on a viberation isolation optical table, captures both reflection and transmission images of sample

Transmission Electronic Microscopy (TEM)

 

widely used to characterize a lot of materials both from a morphological point of view and from the crystallographic but also for the elemental composition. Using TEM a large variety of materials as ceramics, minerals, metals, alloy, semiconductors, glass and polymers can be observed.

Atomic Force Microscope (RT-AFM)


We have an Atomic Force Microscopy (AFM) in which a fine tip is brought into atomically close contact with a sample surface without actually touching the surface. This is done by sensing the atomic force between the probe tip and the surface. The forces are extremely small (about 1nN). The tip is then moved back and forth over the sample surface and can measure the topography with almost atomic resolution

Glovebox

 

This glovebox workstation provides inert gas enviornment, less than 1ppm oxygen and moisture, for the preparation of air/moisture-sensitive samples. The purification system is fully automated and regenerable.

Four-mirror Optical Floating Zone Furnace

 

Up to 120mm single crystal can be grown by this Four-mirror type floating zone furnace, which is made by Crystal Systems Inc.

Pulsed Laser Deposition system (PLD)

 

 The PLD method of thin film growth involves evaporation of a solid target in a High Vacuum chamber by means of short and high-energy laser pulses. In a typical PLD process, a researcher places a ceramic target in a vacuum chamber. A pulsed laser beam vaporizes the surface of the target, and the vapor condenses on a substrate.

High-pressure Synthesis System (Big Blue)

 

Rockland piston-cylinder system with pressure up to 35Kbar  is designed to synthesize high pressure phase of some material which can not be formed at normal  atmosphere.

High Pressure Oxygen Furnace

Upto 400 atomosphere at 1100C, it is an ideal furnace to use for annealing samples, preparing new materials under high pressure, and controlling oxygen stoichiometry.
