Research Activities

Freedom of research ideas and interdisciplinary values are fostered by Applied Research Institute workers, therefore all scientific ideas are evaluated and studied, if they create knowledge and added value.

Currently most of our efforts are directed to these research trends:

Semiconductor materials and devices for optoelectronics

Light emitting diodes (LEDs) are energy efficient light sources providing a novel design and functionality options. LEDs already have dominated in cell phone backlighting, advertising displays, traffic signals, emergency and novel architectural lighting. InGaN-based white LEDs are increasingly used in general lightning. There is also a considerable demand for compact and efficient ultraviolet (UV) light sources for detection of hazardous agents, currency security, disinfection and sterilization. To meet this demand, UV LEDs are being successfully developed using AlGaN alloy.
Currently we are studying the wide-band-gap nitride semiconductors and their heterostructures, investigating the phenomena limiting the LED efficiency, and developing technological solutions to increase LED efficiency. Also we are studying semiconductor and oxide scintillators for high energy physics experiments.
We promote world-class research activities in the field of solid-state lighting. We work on characterization, optimization, and applications of light-emitting diodes (LED) and their systems in general and niche lighting. Main focus is optimization of LEDs clusters and systems by varying spectral power distributions. The equipment (including software) possessed (obtained) by the researchers allows ones to perform a full scale characterization, modelling and optimization of the optical, electrical and thermal characteristics of the LEDs and small LED based systems. We specialize in lighting systems with advanced colour properties (controllable colour saturating, and fidelity) for general lighting as well as lighting systems for the growth of vegetables with improved nutritional quality. The research and modeling of intelligent solid-state lighting systems for outdoor lighting is also within our scientific interest.

Organic semiconductor synthesis, properties, and functional derivatives

Traditional semiconductors are being increasingly replaced by organic materials in the electronic applications. Organic display and lighting technologies are one of the fastest growing in the markets of semiconductor devices (Organic display and lighting technology market are one of the fastest growing in the sector of semiconductor devices). Technologies of organic solar cells, organic circuits and sensors are also rapidly improving. Organic materials enable the fabrication of large, flexible devices by cheap techniques of printing and spin-coating. Moreover, the merging of the fields of organic electronics and biotechnologies brings an enormous potential to the life science technologies. Our main scientific interests are the modification of the properties of multifunctional organic electronic materials, the fabrication of organic nanoparticles and their applications and the improvement of organic device technologies.

Optoelectronic technology

Optoelectronic technologies are the one of most progressing technologies in the world. Development of new cost-effective light emitting diodes (LED), semiconductor lasers, solar cells and their applied research targets nowadays challenges in energetics, security, information technologies. Gallium nitride together with aluminum, indium and boron alloys is the main materials for production of popular ultraviolet and blue LEDs. Today research and industry are solving the problem how to exploit most effectively the broadband feature unique for this material covering the UV-VIS-near IR spectra region to develop new efficient white, deep UV and IR LEDs, solar cells. That would stimulate future development of sustainable technologies for lighting and energetics.
Main activities are carried by the main entity of the new Optoelectronic technology. Central part of it is the new installed metalorganic chemical vapor deposition reactor, giving opportunity to develop new optoelectronic materials, produce device structures. The interest of the team is to develop gallium nitride and alloys technology, to produce and investigate hybrid organic-inorganic interfaces, to create new optoelectronic devices and proceed with new applications.
