X and Q-band EPR spectrometers

Commercial  EPR spectrometers are equipped with gas-flow helium cryostats and controllers developed in the laboratory.  EPR, photo-EPR and electrically detected EPR at 9 and 35 GHz can be studied in the temperature range of 3.5 to 300 K.

ODMR spectrometer

ODMR spectrometer is designed in the laboratory and allows detection of EPR at 9, 35, and 94 GHz by monitoring photoluminescence intensity or polarization and magnetic circular dichroism in absorption in the spectra range of 250 - 2000 nm at a temperature of at 1.8-4.2 K.

Atomic Force Microscopy - Confocal Raman / Fluorescence Microscopy setup NTEGRA-SPECTRA

Integration of scanning probe AFM with confocal Raman/fluorescence allows  to measure simultaneously  AFM and Raman maps of exactly the same sample area and provide complementary information about sample physical properties (AFM) and chemical composition (Raman).

Development of new techniques and experimental equipment for magnetic resonance

A line of high frequency EPR/ODMR spectrometers operating at 35, 78, 95 and 140 GHz

Based on the microwave bridge developed in cooperation with DOK Company we have constructed a prototype of the EPR/ODMR spectrometer operating at 94 GHz. The microwave bridge includes a powerful microwave generator with extremely high frequency stability and an extra sensitive super heterodyne receiver. The bridge is compact and can operate in both cw regime and in pulsed mode with time resolution of 5 ns. Microwave circuit of the spectrometer with the microwave cavity is compatible with standard magneto-optical helium cryostats. Using the same design principles we are planning to develop a line of EPR/ODMR spectrometers operating at 35, 78, 95 and 140 GHz, which can be used for a study and characterization of nanostructures.

Development of a Scanning Probe Optical - Magnetic Resonance Spectrometer

Combination of high spatial resolution of a scanning probe confocal fluorescence microscopy  and magnetic resonance spectroscopy will allow investigating  the  spin properties in small volume of the sample (as small as 5 nm) and to detect single quantum objects
