Profile

I am originally from Bucharest, Romania. As you might suspect, I am a graduate of University of Bucharest and PhD of Institute of Atomic Physics, Bucharest. Since 1996 I am with the Max Planck Institute of Microstructure Physics working on ferroelectrics and direct wafer bonding. For a resume please click here.

Research activities

Thin film growth and characterization: metal oxide ferroelectric thin film deposition, optical and high-frequency applications; pulsed laser deposition, and chemical solution deposition; oxide thin film heterostructures; growth mechanisms and defect structures; structure-property-processing interrelationships; integration of Si and GaAs for device applications.

Nano-fabrication technologies; novel physical phenomena in electronic, and photonic materials with shrinking dimensions. Size effects in nanoscale ferroelectric materials. Physics and micro- and nano-engineering of thin film devices (dielectric or magnetic multi-layers, multi-functional thin film devices, sensors, micro-actuators, non-volatile memories, DRAMs)

  • Information Technologies

Non-volatile information storage technologies: ferroelectric random access memories; integrated optical devices for information processing and storage; "smart" thin film for sensors and actuators, and technology development and marketing. Physics and technology of MOS devices including MFS devices and non-volatile memories. Interfaces (oxides-semiconductor) and interface properties
