Research Topic: Growth and applications of energy related materials as thin films



My name is Natacha Ohannessian, a woman from a tiny village in central France. After two years of Classes Préparatoires aux Grandes Ecoles in Lyon I entered the Ecole Nationale Supérieure de Chimie de Montpellier in France where I studied General Chemistry. As I wanted to specialize in Materials, I went to the Polytechnic School of São Paulo in Brazil in order to learn more about both Physics and Chemistry in that field.

Regarding my working experiences I first performed an internship at the European Membrane Institute in France using the electrospinning process for preventing tumors growth. Then, as I wanted to deepen my knowledge of thin films and deposition methods, I spent one year and a half working for the R&D center of Air Liquide Laboratories in Tsukuba, the Japanese science city. As part of the Electronic Specialty Gases, I mainly used CVD, ALD and PVD processes for thin-films depositions.

These experiences gave me new perspectives on the vast scope of inorganic materials and strengthened my will to keep on pursuing a research career. My one-year-long world trip I previously performed, pushed me to develop a strong interest towards foreign cultures. Therefore, pursuing PhD studies in the Thin Film and Interfaces Group at PSI is a great opportunity for me to join together these important personal features. My main PhD topic is to understand the fundamental growth of oxynitride films deposited with PLD.
