When Herbert Kroemer (Nobel Prize in Physics, ) coined the famous phrase “the interface is the device”, he referred to the success of devices based on thin inorganic semiconductor films for photonic and electronic applications that started more than four decades ago.
This statement also holds for organic semiconductors, which are predestined by deposition on large-area and flexible substrates to be the electrically and optically active layers with important applications in electronics, lighting, photovoltaics and displays. A good number of interfaces (organic/organic and organic/inorganic) are inherent to all organic electronic devices and, because of their relevant role in device performance, Kroemer’s phrase can be extended: “The interface S are the organic device S ”.
With that certainty added to the experience and of the Physical Chemistry of Surfaces and Interfaces (PCSI) group, we offer a doctoral position.
The doctoral project (*) aims to obtain structural control of organic semiconductors thin films for the near future manufacture of more reliable organic electronic devices. The proposal points to a detailed microscopic understanding of crystallography, polymorphism, role of interfaces, as well as to determine the conditions for a good thermal stability of thin films prepared by various physical and chemical methodologies. Furthermore, the use of multi-component thin films (e.G., donor/acceptor organics) and proper fabrication protocols will allow obtaining co-crystalline charge
