In January 2023, the European project Slovak Quantum Communication Infrastructure (skQCI) started, where Institute of Electrical Engineering SAS participates. Project’s main goal is to build a quantum communication infrastructure between cities Bratislava and Košice, connecting 12 Slovak academic institutions. The goal is to improve information and communication security at the level of state institutions, security…
We have recently hosted a Taiwanese delegation of semiconductor industry experts from Industrial Technology Research Institute (ITRI), Taiwan. The delegation members included ITRI VPs Dr. Pei-Zen Chang & Dr. Chih-I Wu with their colleagues and Mr. David Nan-Yang Lee from Taipei Representative Office Bratislava. A fruiful discussion included our research topics and identified several points…
On April 15, 2020, the Crisis Assembly (CA) of IEE SAS met and agreed on the further instructions for the upcoming period: The heads of the scientific departments provide the signed documents ‘Home office work description’ for the month of March and April (from 10.3.2020) to the IEE management, describing activities related to work at…
On 30.3. In 2020, the Crisis Assembly (CA) of IEE SAS met and agreed on further instructions and rules for the upcoming period: The heads of the scientific departments will provide the Institute management with signed documents of the “home office” for the previous month (from 10.3.2020 inclusive), describing activities of workers during their work…
Terahertz (THz) waves fall between microwave and infrared radiation in the electromagnetic spectrum, oscillating at frequencies of between 100 billion and 30 trillion cycles per second. These waves are prized for their distinctive properties: they can penetrate paper, clothing, wood, and walls, as well as detect air pollution. THz sources could revolutionize security and medical…
Researchers at the University of Rome Tor Vergata, the Italian Institute of Technology (IIT) and its spin-off, Graphene Flagship Associate Member BeDimensional, in cooperation with ENEA have successfully combined graphene with tandem perovskite-silicon solar cells to achieve efficiencies of up to 26.3%. Moreover, they envisioned a new manufacturing method that, thanks to the versatility of…
In infrared images, hot objects usually radiate brighter than cooler. But the newly designed protective layer breaks the rule that hot equals brighter. At certain wavelengths of infrared light, the brightness of the material does not change even when heated. A report on this discovery was published on December 17 in the proceedings of the…
Materials such as oxide layers represent a modern trend in the development of superconducting structures. Current areas of research include the study of oxide layers, either directly dielectric layers or metal oxide layers, where great attention is paid to the preparation and properties of layers and structures with a perovskite structure. For the realization of…
Physicist Joel Therrien of the University of Massachusetts in Lowell introduced a new form of carbon called “U-carbon” at the International Symposium on Clusters and Nanomaterials in Virginia, USA. This material should be characterized by a high hardness (greater than stainless steel) and conductivity and reflectivity comparable to those of a polished aluminum mirror. Perhaps…
Semiconductors are materials that, from the point of view of electrical conductivity, are between electrically conductive and non-conductive materials. Scientists’ interest in semiconductors increased considerably after the first transistor was created in 1957. “Today, it is clear to everyone that without semiconductors and complex integrated circuits prepared from them, there would be no modern…
