MIPT is one of the leading universities in the areas of physics, mathematics, and informatics. The institute holds a leading position in Russia in quality recruitment and qualified graduate training. Students and graduates of MIPT are representatives of an elite circle who, thanks to their interdisciplinary scientific surroundings, are able to fully realize their potential.
The unique “Fiztech System” is one of the best approaches to education, which explains its existence in an almost unchanged form for more that 60 years. Receiving a fundamental education in mathematics and physics and a preliminary acquaintance with the chosen specialization, along with the acquisition of skills in independent work already by the 4th course provides each student with the knowledge and experience of a full scholar. Thus, by the end of the program, students already have significant achievements in their chosen area of activity.
In the present age of digital technology, time plays a particularly important role. Education of a difficult and protracted nature allows students and graduates of MIPT to always be in the trend of world science and to adapt to sudden changes in the situation.
Student life at MIPT is rich and diverse. Students actively combine educational activities with sports, participation in cultural events, as well as their creative endeavors. The administration at the institute strongly supports this initiative and cares about the welfare of its students. Thus, it is constantly working to expand the campus and interests of students.
The recently demonstrated electroluminescence of color centers in diamond makes them one of the best candidates for room temperature single-photon sources. However, the reported emission rates are far off what can be achieved by state-of-the-art electrically driven epitaxial quantum dots. Since the electroluminescence mechanism has not yet been elucidated, it is not clear to what extent the emission rate can be increased. Here we develop a theoretical framework to study single-photon emission from color centers in diamond under electrical pumping. The proposed model comprises electron and hole trapping and releasing, transitions between the ground and excited states of the color center as well as structural transformations of the center due to carrier trapping. It provides the possibility to predict both the photon emission rate and the wavelength of emitted photons. Self-consistent numerical simulations of the single-photon emitting diode based on the proposed model show that the photon emission rate can be as high as 100 kcounts s−1 at standard conditions. In contrast to most optoelectronic devices, the emission rate steadily increases with the device temperature achieving of more than 100 Mcount s−1 at 500 K, which is highly advantageous for practical applications. These results demonstrate the potential of color centers in diamond as electrically driven non-classical light emitters and provide a foundation for the design and development of single-photon sources for optical quantum computation and quantum communication networks operating at room and higher temperatures.
