Q & A:

What is a science philosophy ?

There is only one way to understand our nature, it is a battle with your own: compromise between the correct and wrong vision of the problem solution.

Solution of the problem always related to the understanding how we can make simplification of the system which exlore. And science is a ladder by which you go upstairs all the time solving more complicated problems than previous, building novel problems, which, as we think, will cover growing number of questions.. So, science is not only nature explore, it is the way for self-improvement. And this is wonderful chalenge as a goal of life!

Goals

Prof. Useinov focuses on analytical and theoretical modeling of the nanoscale devices: e.g. magnetic/ferroelectric tunnel junctions, memristors, domain wall resistance, using hand-made programming. All begins from the energy potential barrier simulation, then finding the related probability of electron transparency (scattering) for this barrier, and finally, the simulation of I-V curves, that is one of the important step for further IC simulation, if it designed together with the novel device. Building a compact model is also a related problem for a combined IC simulation. I-V curves can be simulated in different approaches, one of them is the developed point-contact model, which discovered as a most precise model for both macroscale and nanoscale systems.

Laboratory is also equipped by scanning probe microscope, and it is possible to confirm the theoretical simulations by experiments. Exploring the system make an experimental support.

Research & skills

Research: Transfer matrix and point-contact models. Any complexity I-V curve simulation. SPM(AFM) and STM methodology. Tunneling phenomena. Basics of programming, material science and quantum physics.

Self-improvement skills: become more accurate and behave cleverer; to see the differences in subsystems; filling of data and numbers, which are usually hidden from usual eye; to be self-motivated, to be smart in programming, the techniques which allow to solve numerous problems. Writing paper & vector graphics skills.
