Organization structure and principal activities
General Information
The Institute of Electronics and Photonics (IEP/ÚEF in Slovak) provides an education and carries out a research work in a very wide range of micro-/nanoelectronics, photonics and sensorics. Topics from physical principles, technology, materials and structure analysis to system design and applications are covered.
Courses like Materials for Electronics, Electronic Devices, Sensorics, Optoelectronics, Signals and Systems, Electronic Circuits, Microprocessors and Microcomputers as well as Audio and Video Technology are provided for undergraduate students. More specialized courses are offered mainly for 2 MSc study programs called “Radio and Electronic Engineering” and “Microelectronics”.
Research and development activity of the Institute staff is oriented as follows:
– Technology and parameters of gas sensors using NiO and TiO2 thin films and nanotips, including growth of a sensitive layer on Si nanotips were analysed and biosensors using Au plasmonic nanoparticle islands on ZnO nanotips were also investigated.
– Research is focused on the synthesis, analysis and applications of carbon nanomaterials. Deposition of intrinsic and boron doped diamond thin films (BDD), DLC layers, carbon nanowalls (CNW), nanotubes (CNT) and graphene is performed by CVD techniques. The synthesized nanomaterials are used for applications in electrochemical analysis and water treatment. The occurrence and concentrations of heavy metals, pesticides, drugs and pharmaceuticals in environment and wastewaters is investigated. The degradation efficiency of these micropollutants by BDD electrodes is studied as well.
– Preparation and analysis of organic layers (e.g. conductive doped PEDOT:PSS, passivation parylen C layers) for organic electronics have been investigated and flexible electrodes for biosignal measurement were verified experimentally. Efficiency of OLED has been increased using photonic crystal based on SiO2 nanoparticles. Complete production line to prepare OLED, OFET and photovoltaic structures has been build up.
– 2D/3D electro-physical modelling and simulation has been used for analysis and optimization of progressive structures and devices, e.g. photovoltaic structures and power devices. New advanced methodology for effective 3D electro-thermal device simulation has been proposed.
– Integrated circuit and systems design and test activities were focused on development and integration of energy efficient circuits for different smart wireless sensors, specifically, for implantable biomonitoring devices and smart wireless metering in households.
– Wireless sensor network for non-invasive in-field EMG and ECG bio-signal measurement synchronized with 10D IMU has been developed and experimentally verified in a number of applications. System is supported by software toolchain for data analysis.
– Progressive solutions of circuits widely used in radio-communication systems, e. g.: local wireless communication networks (WiFi, Bluetooth, ZigBee), cellular communication networks (GSM, UMTS, LTE), software defined radios (SDR), global navigation satellite systems (GPS, Glonass, Galileo), radar systems, RFID, etc. Research is devoted to investigation and to design of novel concepts of signal generators and oscillators with low phase noise, Phase-Locked Loops (PLL), Direct Digital Synthesizers (DDS), secondary frequency standards, etc.
– Research work is concentrated also on image processing: edge detection with sub-pixel accuracy, localization in 3D space based on two cameras.
Cleanrooms ISO5 are equipped with a deposition and etching apparatus and lithography. Material and structure analyses was performed using AES, SIMS, AFM incl. STM, EFM etc., SEM, EBIC, CL, PL, micro-Raman spectroscopy, spectral ellipsometer. Properties and parameters of prepared structures and devices are evaluated using electrical and optical measurement (I-V, C-V, DLTS, microwave and time-resolved measurement, noise analyses while emphasis is put mainly on GaN (HEMT) and SiC structures. EUROPRACTICE membership provides an access to advanced modelling and system design tools as well as to prototyping.
The Institute was involved in 9 EU funded projects (3 FP7, 2 ENIAC JU, 1 COST, 3 HORIZON 2020). Researchers of the Institute have been acknowledged as a “University Top Research Team” (one of two Slovak teams in the area of electrical and electronic engineering) by the Accreditation Commission of the Slovak Republic.
