Facilities

Clean room

The cleanroom is installed in the Department of Applied Physics of NTUA and it is operational since May 2006. It includes infrastructure for gas distribution, compressed air and vacuum as well as for the provision of de-ionized water with resistivity up to 15 MΩ. Samples are cleaned and dried under class 100 hood areas.

Vacuum deposition chamber

A high vacuum chamber is installed in our clean room and it is equipped with three RF sputtering sources and a nanoparticle DC sputtering source.

The RF sources are used for the deposition of thin films either metallic (Ti, Pt, V) or dielectric (TiO₂, V₂O₅, VO₂, HfO₂ etc.)

The Nanogen DC nanoparticle source can synthesize and deposit nanoparticles from metallic sources in diameters ranging from 2 to 14 nm and various aerial densities.

Equipment

• 3× Kurt J. Lesker RF Sputtering sources that can operate independently
• 1× Nanogen Magnetron DC Nanoparticle source manufactured by Mantis Deposition Ltd.
• 1× Thermal evaporator for the deposition of Aluminium films
• 1× E-gun evaporator for the deposition of refractory and precious metals with high control of the film thickness

Atomic Layer Deposition

A Picosun R200 Atomic Layer Deposition System is operational since January 2016.

Laser thermal processing laboratory

An industrial CO₂ laser manufactured by Millenium Lasers Ltd. for the annealing and thermal treatment of semiconductors is installed in our laboratory. The laser can deliver pulses up to 10 kW·cm^-2 in the millisecond regime. The setup is also equipped with a heated sample holder (up to 1000°C) to aid the absorption of the radiation in lightly doped semiconductors.
