Experimental facilities: 

The Center for Solid State Physics and New Materials consists of several laboratories:

Laboratory for crystal growth and material synthesis is equipped with several crystal growth techniques like Czochralski, Bridgeman or floating zone, thin film technology methods (thermal evaporation, spattering, laser ablation), sol-gel technology, sintering, etc. 

Laboratory for photoluminescence and Raman scattering spectroscopies is equipped with double grating U1000 Jobin Yvon monochromator, Ar, Kr, He-Ne and He-Cd ion lasers, and Peltier effect cooled photomultiplier (model RCA 31034A) as a detector (single photon counting detection system). For low-temperature measurements (10K-400K) there is the Leybold closed cycle helium cryostat. This experimental set-up has an excellent stray-light rejection and allows the measurements close to the laser line. 

Laboratory for micro-Raman spectroscopy is equipped with triple Jobin Yvon T 64000 spectrometer (gratings with 1800 grooves/mm), Coherent Ar- Kr mixed gas ion laser, and CCD detection system. The set-up contains a confocal microscope and x-y-z microscope stage. For variable temperature measurements there is a Linkam THMS 600 heating and cooling microscope stage, which allows the micro-Raman measurements in the temperature range between 77 and 900K. Another micro-Raman set-up is TriVista TR557 spectrometer.

The TriVista TR557 spectrometer is the most flexible system for Raman and photoluminescence measurements. Three imaging corrected spectrometers of 500 mm and 750 mm focal length yield an excellent stray light rejection (capture Raman spectra as close as 5 cm 1 from the Rayleigh line) with best resolution (<0.004 nm). The optical design enables to switch between additive mode and subtractive mode without an additional optic. The working range of the TR557 is from UV (185 nm) to near IR (2.2 mm), depending on the grating and detector selection. TriVista system is equipped with CCD detector, confocal microscope and the software-driven XYZ stage enables automated 3D mapping with an auto focus option. For variable temperature measurements under microscope we supplied Linkam THMSG 600 heating/freezing stage which works in temperature range -196° to 600°C, up to 130°C/min heating and temperature stability <0.1°C.

Laboratory for Fourier transform Infrared (FTIR) spectroscopy and ellipsometry is equipped with two FTIR systems: Bomem DA-8, and SPECAC spectrometers. The first system allows the measurements in the wide frequency range (30-25000 cm^-1) at temperatures between 4 and 300 K. The second set-up provides the excellent conditions for the measurements in the low-frequency region (1-250 cm^-1) in the 77-300 K temperature range. 

High Resolution Variable Angle Spectroscopic Ellipsometer (SOPRA GES5E - IRSE) can measure the dielectric constants of different materials and thin films in the wide spectral range from 190 nm to 28 µm at temperatures between 10K and 400 K using ARS Inc. low vibration closed cycle cryostat, Model CS204SE-X20(OM).

Laboratory for galvano-magnetic measurements (Hall effect set-up) is equipped with conventional electro-magnet (magnetic field up to 1.5 T), Hall effect set-up and ARS Displex DE-202N closed-cycle-helium cryostat (for low temperature measurements between 6 and 300 K). 

Laboratory for magneto-optic and magnetic measurements is equipped with 14 T cryogen free measurements system (Cryogenic Ltd. superconducting magnet with vibrating sample magnetometer, resistivity and Hall effect set-up, specific heat system). This system has an optical window (at the bottom) for base of cryostat for optical connection with TriVista TR557 triple Raman system (S&I GmbH) for low temperature and high magnetic field Raman and photoluminescence measurements, which is also part of this Laboratory.

Laboratory for nanoscopy is equipped with state of art equipments for measuring the properties of materials at nano-level (Omicron variable temperature SPM and AFM, model B002645 SPM PROBE VT AFM 25 with MATRIX control system, SNOM, model TwinSNOM R).

Knowledge:

This Centre offers its advanced experimental and theoretical tools: A family of optical spectroscopy (FTIR, Raman, Ellipsometry, PL) as well as nano-spectroscopy (AFM, STM, SNOM) methods. In the past, this group established a scientific collaboration on the bilateral basis with many of European laboratories, so the European funding of OPSA  project would be a natural continuation of these collaborations, and should provide an essential step further towards the scientific excellence. The scientists participating in this project have published more than 350 scientific papers in well reputed international journals.
