INNOVATIVE TOPOLOGICAL ROUTES

Open days at Jozef Stefan Institute, Slovenia

for schoolchildren and their parents

for everyone interested in modern developments in science


Mar. 2024. Dr Anna Razumnaya, within EU-FerroChiral project, organized a presentation on an open day at Jozef Stefan Institute. 


Information about ferroic materials was presented with outstanding properties potentially useful for applications in different fields of science and technology.

Open-door day at the University of Picardy Jules Verne, France


Feb. 2024. An international team consisting of participants from three European Marie Curie mobility projects: RISE-MELON: Igor Lukyanchuk (France) and Marcelo Sepliarsky (Argentina)  ITN-MANIC: Yurii Tikhonov and IF-FerroChiral: Anna Razumnaya organized a presentation at an open-door day at the University of Picardy, UPJV. Schoolchildren planning to enter the university enjoyed listening to the explanation of scientists about future computers that will be based on new principles of neuromorphic and multilevel logic, as well as about the possibility of controlling chirality by electrical switching.

The university expressed gratitude to the researchers.

The ferroelectric FET with negative capacitance

Integrating negative capacitance into the field-effect transistors (FET) promises to break fundamental limits of power dissipation known as Boltzmann tyranny. However, realization of the stable static negative capacitance in the non-transient regime without hysteresis remains a daunting task. Here we put forth an ingenious design for the ferroelectric domain-based FET with the stable reversible static negative capacitance.

Modern microelectronics is currently facing a profound challenge. The demand for even smaller and more closely packed electronics has hit a stumbling block: the power emitted in these devices releases more heat than can be efficiently removed. Now, Professors Valerii Vinokur, Anna Razumnaya, and Igor Lukyanchuk propose a solution based on the seemingly counterintuitive phenomenon of ‘negative capacitance’. The effect is surprisingly linked to an intriguing topological structure, which is found time and again across a broad range of scientific fields.
