Scientific expertise |
Dr. Leontin Padurariu (LP) is lecturer at Faculty of Physics from Alexandru loan Cuza University of lasi, Romania, and he has 10 years of experience as researcher. He obtained the PhD title in 2015. The major interest was dedicated to developing numerical models (based on Finite Element Method, Monte Carlo, Landau theory, Preisach model) for describing dielectric, ferroelectric, mechanical, energy storage properties of heterogenous structures. More recently, LP started to develop a novel dynamic FEM-based approach to describe the conductive properties of real dielectric/ferroelectric based composites. The scientific activity was materialized so far in 26 ISI paper, most of them being classified as Q1, and a Hirsch factor of 13. Over ten articles co-authored by LP are related to BaTiO3 or Pb(Ti,Zr)O3 — based porous materials |

Capabilities |
Using the modeling capabilities, LP proposed the idea of designing special microstructure with advantageous configurations of the local electric field and this concept was named local field engineering. More recently, Leontin Padurariu extended the concept of local field engineering towards composite materials with semiconductor character in a new comprehensive approach name charged defects engineering. In porous materials the contrast between the permittivity and conductivity values between phases (bulk and air) is maximized and, therefore, it is very interested to study such materials because the field inhomogeneity play a major role on the functional properties. During the present project, LP will be able to perform complementary and innovative modelling activities regarding the dielectric/semiconductor properties of porous materials |
