RESEARCH FACILITIES
Thin Film Laboratory:
The Thin Film Laboratory facilitates the preparation and study of thin films for device applications.
1. Spray Pyrolysis Equipment:
Holmarc’s Spray Pyrolysis system has been designed for research laboratories in thin films, especially for solar cell development. The system automates various fatigue and error creating processes involved in the technique when performed manually. Moreover, ergonomically designed chamber provides clean and healthy atmosphere suitable for modern lab conditions.
Parameters like dispensing rate of the solution and speed of spray head movement, which are difficult to control manually, are controlled precisely by PC based automation. A positive displacement pump controlled by stepper motor and microprocessor is used to dispense solution as per requirement. The spray head movement is also controlled by stepper motor driven linear stages in X and Y direction. The temperature of the substrate heater plate is controlled independently through a dedicated controller.
Model: HO-TH-04, Substrate temperature: 0 – 500 °C, Spray rate: 1 mL – 10 mL per minute.
2. Thermal Evaporation Unit (Vacuum deposition system):
The basic process of this method is sublimating source material(s) in powder form at high temperature, and a subsequent deposition of the vapor in a certain temperature region to form desired nanostructures.
This system uses resistive heating in which the material is heated until evaporation by means of an electrical current passing through a filament or metal plate where the material is deposited (Joule effect). The material vapor thus condenses in theform of thin film and deposits on the cold substrate surface placed in the chamber. This particular unit has a special arrangement of substrate heating up to 850°C in high vacuum.
Z-Scan system
The Z-scan technique is a simple and popular experimental technique to measure nonlinear optical properties of materials. In this method, the sample is translated in the Z direction along the axis of a focused Gaussian beam and the far field intensity is measured as a function of sample position. Standard open aperture and closed aperture z-scan are covered with the kit. The two measurable quantities connected with the z-scan are nonlinear absorption and nonlinear refraction. These parameters are associated with the imaginary and real part of the third order nonlinear susceptibility, and provide important information about the properties of the material.Z-scan system has 532nm wavelength DPSS CW Laser with up to 100mW power and dual channel detector measurement unit with 2 Si Photodiode detectors and software.
The crystal growth apparatus (Rotek) is used for growing single crystals of organic and inorganic compounds at different temperature conditions (-20 °C to 50 °C) using slow solvent evaporation technique. The grown crystals can be characterized for structural, thermal and for nonlinear optical (NLO) applications.
