Ultradense and Ultrastable molecular glasses by molecular beam deposition.

The project will make use of slow vapour deposition of organic molecules from the gas phase on a cooled target where T < Tg in
order to produce ultra-dense glasses. Different molecular glass formers
will be deposited in order
to study the physics of glasses and supercooled liquids particularly the
role of local phenomena and spatial heterogenities. The project also
aims at investigating the dynamics and thermal signature of ultra-dense
glasses by employing dielectric spectroscopy
and ac calorimetry on the low temperature deposited molecular liquids
and oligomers. This will be done with an aim of addressing some
fundamental questions in the physics of glass forming liquids in bulk or
in thin film geometry.
