Title: Alignment of carbon nanotubes in aerosol for advanced optics and electronics

Abstract: The alignment of carbon nanotubes (CNTs) is of great importance for the fabrication of electronic devices, as the electron mobilities can be greatly enhanced with aligned CNT architectures. Commonly used methods for alignment of carbon nanotubes are based on processing of CNT dispersions and accompanied with many drawbacks. The orientation of CNTs in aerosol is more advantageous yet is little studied because of necessity to use more complex approaches. Existed methods like flow arrangement approach or exposure of CNT aerosol to electric fields are still needed to be improved and their combination haven’t been studied. The combination of these two techniques is expected to solve the problems of CNT application in such advanced devices as single-photon emitter, transistors, thermoelectric components etc.

 Bio: Nikita Raginov is a 3^rd year PhD student in Physics. He is working in the Laboratory of Nanomaterials under the supervision of Prof. Albert Nasibulin. His scientific interests lie in the field of carbon-based nanomaterials, their synthesis by catalytic chemical vapor deposition method and characterization. He is working on projects related to the design and assembly of aerosol-CVD reactors.

Title: Color centers in diamonds as sources of non-classic light

Abstract: Color centers in diamonds attract significant scientific attention due to their unique photophysical properties. The beginning of the diamond color centers era was associated with first studies of Nitrogen-Vacancy color centers that showed high potential for their use as magnetic field sensorics, single photon sources, and most importantly for quantum memory applications. Since then researchers were eager to create other impurity centers in diamonds with even better properties, and now there are more than a hundred of different color centers. Diamond itself is highly biocompatible, allowing use of considered color centers in biological applications such as bio-markering, all-optical thermometry (including intracellular thermometry). Thus, the range of applications of diamonds with impurity centers is quite broad. During the seminar we will discuss new class of impurity centers in diamonds that was discovered within the framework of my PhD research.
