Dear Colleagues,

the next MFA Seminar is out of the normal schedule:

FRIDAY, 2007-10-19 11:00

the location is - as usual:

MFA Meeting Room (KFKI Campus, Bldg. 26, 1st floor)

The speaker is

Patrick G. Soukiassian
Director - "SIMA" Laboratory
Commissariat á l’Energie Atomique,
Saclay and Université Paris-Sud,
Orsay, France

His is going to talk about:

*Amazing Nanochemistry at SiC Surfaces and Interfaces*

The abstract is attached below.

We welcome everyone interested!

Z. Hajnal



Silicon carbide (SiC) is a wide band gap IV-IV compound semiconductor
having strong interest in advanced device/sensor applications, and in

Cubic/hexagonal SiC surfaces and interfaces are investigated by
atom-resolved scanning tunneling microscopy/spectroscopy, core
level/valence band photoemission spectroscopies using synchrotron
radiation and infrared absorption spectroscopy. Such important issues as
i) self-formation of atomic lines having unprecedented characteristics,
ii) diamond-type transformation of C-terminated surface, insulator/SiC
interface formation, atomic scale surface passivation and/or
metallization by O2/H2 will be discussed.

In particular, the first observation of a semiconductor surface
metallization induced by atomic hydrogen will be presented. Such a
finding directly impacts the ability to eliminate electronic defects at
semiconductor interfaces critical for microelectronics, provides means
to develop electrical contacts on high band-gap chemically passive
materials, particularly exciting for interfacing with biological
systems, and gives control of surfaces for lubrication, e.g. for
nanomechanical devices.
