Synthesis
Magnetron Sputtering for Thin-film Growth
Magnetron sputtering is a Physical Vapor Deposition (PVD) technique used to synthesize high-quality epitaxial thin films—single-crystal layers grown with a specific crystallographic orientation relative to a single-crystal substrate. It is preferred in industrial and research settings for its scalability, high deposition rates, and ability to grow complex oxides and nitrides at relatively lower temperatures compared to traditional vapor phase epitaxy.
Tube Furnace
Compact vacuum tube furnace (1100-degC) for sintering, annealing and substrate treatment with the facility of O2/Ar gas flow.
High-Temperature Box Furnace
Compact high-temperature box furnace (1700-degC) for target sintering, densification, and annealing.
Characterizations
The D8 DISCOVER is the flagship multi-purpose X-ray diffractometer offering leading technology components. It is designed for the structural characterization of the full range of materials from powders, amorphous and polycrystalline materials to epitaxial multi-layered thin films at ambient and non-ambient conditions.
The MultiMode® platform's long history of success is based on its combination of superior resolution, performance, and unparalleled versatility and productivity. The MultiMode 8-HR atomic force microscope (AFM) further advances these capabilities to provide significant improvements in imaging speed, resolution, and nanomechanical performance with higher speed PeakForce Tapping®, enhanced PeakForce QNM®, new FASTForce Volume, and exclusive Bruker probes technology.
The popular Physical Property Measurement System (PPMS) from Quantum Design is now available in a truly cryogen-free package. The PPMS DynaCool uses a single two-stage Pulse Tube cooler to cool both the superconducting magnet and the temperature control system, providing a low vibration environment for sample measurements. It offers continuous low temperature control and precise field and temperature sweep modes.
Improved accuracy in both resistivity and Hall coefficient measurements is possible using the van der Pauw technique. This Option utilizes a switching controller to automatically collect data necessary to accurately calculate parameters such as carrier concentration and sheet resistance for a uniformly thick sample of arbitrary shape.
The Horizontal Rotator enables a transport sample to be rotated over a full 360° in the presence of an applied magnetic field. An automated indexing procedure and encoder ensures accurate angular positions and the on-board thermometer monitors the temperature in close proximity to the sample.
SQUID Magnetometer: Quantum Design MPMS®3
Quantum Design's MPMS 3 represents the culmination of 40 years of development and design in the world of SQUID Magnetometry. Providing users with the sensitivity of a SQUID (Superconducting QUantum Interference Device) magnetometer and the choice of multiple measurement modes, the MPMS 3 offers new levels of performance in magnetic research while including those aspects of past Quantum Design SQUID magnetometers that customers have grown to appreciate and depend on.
Quantum Scanning Microscope (NV-magnetometer)
Quantum scanning microscope uses a single defect in diamond, a Nitrogen Vacancy (NV) center, as an atomic size quantum sensor. By scanning it in close proximity over a sample surface, we can quantitatively map magnetic fields and more with high sensitivity and better than 40 nm resolution. All of this works in ambient conditions, in the desktop sized QSM. Removing two adjacent carbon atoms from the diamond crystal lattice and placing a nitrogen atom at one of the sites creates an NV center.
X-ray Photoelectron Spectroscopy
X-ray Photoelectron Spectroscopy (XPS) is a powerful surface-sensitive analytical technique that uses X-rays to eject core-level electrons from a material, allowing analysis of its elemental composition, chemical states, and electronic structure within the top few nanometers. By measuring the kinetic energy of these emitted photoelectrons and applying the photoelectric effect equation, scientists can determine binding energies, identifying elements and their bonding environments, making it crucial for materials science, catalysis, and environmental studies.
