Chamber furnace is used for synthesis of oxide materials using solid state reaction.
It is also used for single crystal growth using flux method.
The furnace is used for annealing of the samples at higher temperatures (up to 1200 °C).
The arc-melting furnace is used for the preparation of polycrystalline samples in the Argon atmosphere.
We prepare the polycrystalline samples of a variety of inter-metallic alloys using this system.

Glove Box with Integrated Evaporator
The glove box offers a sealed inert (N2 or Ar) environment where device fabrications can thrive without interference from air or moisture, serving as miniature labs, enabling high-precision fabrication in a contamination-free zone.
This controlled atmosphere is especially crucial for handling sensitive compounds. Glove boxes ensure the stability and integrity of these fragile materials by maintaining ultra-low humidity and oxygen levels.
The system is integrated with a thermal evaporator and e-beam to make electrical contacts in a device. In addition, it also has a spin-coater, weighing balance, hot plate, etc, for fabrication of a full device in an inert atmosphere.
Solar Simulator:-
A solar simulator replicates the solar spectrum (AM1.5G) inside the lab. It is essential for the electrical characterization of solar cells to evaluate short circuit current density (JSC), open-circuit voltage (VOC), fill factor (FF), and power conversion efficiency (PCE).
This allows researchers and manufacturers to optimize solar technologies' efficiency, reliability, and real-world readiness—all under one sun, indoors.
Quantum Efficiency Measurement System:-
Quantum efficiency measurement evaluates the spectral performance of light-sensitive devices like solar cells, photodetectors, and image sensors.
It measures how effectively incoming photons are converted into electrical current, revealing the actual responsiveness of a device to different wavelengths of light.
Four-point probe:-
The tool is used for determining sheet resistance of conducting thin films.
