Beneficiary of the competition "Encouraging young scientists for publication of scientific articles".

A. of the Armenian-Russian University and RA NAS. Sargis Gavalajyan, a researcher at the Institute of Chemical Physics named after Nalbandian, was recognized as a beneficiary of the competition "Encouraging young scientists for the publication of scientific articles" held within the framework of the "Support Program for Young Scientists".

A young scientist has been recognized as a beneficiary for the publication of a scientific article for the first time in the top quarter of the journal classification in "Scimago Journal & Country Ranking (SJR)". Presented by "Optical Properties of Conical Quantum Dot. Exciton-Related Raman Scattering, Interband Absorption and Photoluminescence" scientific article published in the journal "Nanomaterials". Co-authors are Grigor Mantashyan, Gor Kharatyan, Hayk Sarkisyan, Pagytar Mantashyan, Davit Hayrapetyan and Professor Baskoutas Sotirios of the University of Patras, Greece.

Sargis Gavalajyan mentioned that the basis of the scientific article is his diploma work on the topic "Optical properties of a conical quantum dot: excitonic Raman scattering, interband absorption and photoluminescence". "The goal of the work was to show how efficiently conical semiconductor quantum dots can be used as a light source," he said. According to the author, the obtained results allow a better understanding of the optical properties of conical quantum dots and may be useful for the design of new photonic devices. “They can be used to engineer the size and composition of quantum dots to achieve specific optical properties, such as narrow beam widths or high photoluminescence quantum yields. These properties are important for the design of high-performance photonic devices such as lasers, displays, and sensors. In another case, by designing the band structure of quantum dots, it is possible to enhance light absorption and charge separation in solar cells," Sargis Gavalajyan presented.

Currently, Sargis is studying in the 2nd year of his master's degree at the Department of Electronics and Nanoelectronics of the Armenian-Russian University. He says about his choice of profession: "Physics is perfect for working with numbers and looking for explanations for the phenomena around us. Physics is an art. In order to do physics, it is necessary to get out of the standard way of thinking."

Sargis Gavalajyan is involved in the "2023 Program for the Establishment of Remote Laboratories" of the Higher Education and Science Committee of the Armenian National Academy of Sciences of the Republic of Armenia, the grant program of the Yervand Terzyan Armenian National Science and Education Foundation (ANSEF) and the EU "H2020 NanoQIQO" program. Researches semiconductor quantum nanostructures as the basic foundation of new generation optoelectronic devices. He is also engaged in the organization of scientific schools, seminars and conferences. Cooperates with international student organizations such as SPIE and OPTICA.

Among the most impressive events of his scientific activity, he considers the meeting with the Canadian optical physicist Donna Strickland, who received the Nobel Prize in 2018 with the French physicist Gérard Mourou for discovering the amplification of activated pulses. "In Armenia in 2022, I had the opportunity to listen to his lectures related to his research and learn about his path to receiving the Nobel Prize," said Sargis Gavalajyan. Emphasizes the activity of scientific initiatives. "For example, "Gituzh" is a good platform for popularizing science in Armenia and encouraging scientists."

Sargis Gavalajyan generally considers failures as motivation to achieve more. "One should always learn from mistakes and move forward. A modern scientist must be inquisitive, creative and adaptable, with strong critical thinking and communication skills.” Sargis Gavalajyan's scientific dream is to win the Nobel Prize.

We wish him success.
