 So, my name is Christina Buffer and I'm working at the Framico Institute of Applied Polymer Research, which is located in Potsdam-Golm, close to Berlin, in the southwest of Berlin. And we are concerned with many types of polymers starting from bio-polymers up to electrical conducting polymers. And so, I am personally in the division of functional polymers and devices and we are working on organic electronic device development and also deep material development. At the Framhofer IAP? At the Framhofer IAP, yes. And, for example, behind you I see something to do with quantum dots, organic light emitting diodes, OLEDs, and what would you like to talk about first? As I already mentioned in the introduction, we are working on organic electronics in general and we have been busy in this field for 25 years starting this OLED research. So, we are working on development of OLED materials and OLED device stacks and this is a field that we are still working on. About 12 years ago we started to work on quantum dot development so we are focusing on the development of quantum free quantum dots, so-called eco-friendly quantum dots. Our focus is on materials based on indium phosphide, for red and green emission and on zinc-cellenite for blue emission. We have some examples here on the poster so you can see here devices that were made from red and green indium phosphide and the blue zinc-cellenite which was docked with a tellurium. And the second focus that we have besides the material development is the development of processing technologies. So one of the focus is setting up instrumentations and process technologies that are able to make processes for the manufacturing of organic electronic devices. And this is a combination of methods which are suitable to do large area processing such as a slotted coating or for lab-scale tests of spin coating or plate coating. And we also are using digital processes and our focus is on inkjet printing and EHD jet-printing. The inkjet printing is limited with respect to the ink formulations to low viscosity inks and a resolution I would say down to 20 to 40 micrometers. EHD jet has the advantage to be able to print a resolution. For instance here you see an example where we have a dot size of about 10 micrometers and also the same as here. And the second advantage of the EHD jet is that the viscosity range that is accessible is larger than the inkjet so we have a viscosity range that is covering 4 orders of magnitude and so in this case here we have been printed quantum dot materials into a band structure that we resolved in the resin and these structures have a height of a micrometer and we can even make them thicker if we have the right band structure to print in. And these are examples that may be used later on as color filters for instance for micro LEDs. So Fraunhofer is famous for developing, inventing a whole bunch of crucial stuff that's just being used by billions of people every day and it could be in audio and displays and a lot of stuff is happening in a nano technology world right? That's true, yeah. Yeah I may show just goes through some examples. For instance here we have been active in a binational project with a company in France and a company in Germany for developing processes for ambient solution processing of OLEDs in order to address by inkjet printing customized applications that could be used for also small scale and cheap or low cost production of OLEDs. Another example is shown here where we did a high resolution printing using the AEG Jet. This is an active matrix OLED and we printed one layer by AEG Jet into the pixel defining layer of this type of active matrix backplane and then finished the display by spin printing in this place and what you see is the local of this AU project and this system has 20, 60, 4000 single pixels that need to be printed and our goal is to make such a process scalable really to large scale that it may be used into production later on. This is all fascinating stuff and when you develop this stuff you have prototypes but then you work in collaboration with other companies that want to mass produce this. Yeah, that's true. There's one example shown here, this was a collaboration with different companies where a pilot line has been developed within this project in order to do a mass production of these types of barcodes and our goal in this project was to develop the printing processes by inkjet in a way that it can be scalable and can be set into mass production. The requirement here was to achieve a print process that allows printing of a substrate of 400 times 500 millimeters within two minutes to do the whole processing and printing, trying steps with this type of repetition rate. Alright, and we're just at one poster. You have another one? Another poster shows the capabilities that we have in our institute. So what you see here, this is a view in our clean room. We have a clean room capacity of about 300 square meters and this clean room is equipped with all the equipment that you need for the processing of organic electronic devices. So you see here, a picture of our pilot line, it's 50 meters long and we have the different deposition processes sent into the pilot line, we have the inkjet printing, we have the 38 coating, we have the PVE deposition, the lamination and we also have an atomic layer deposition for the encapsulation and we are carrying out different projects in the moment to use the AAG for either encapsulation of organic electronic devices where we need barrier performance properties of 10 to the minus 6 gram per square meter a day and we are also working on the deposition of noble metals for instance for applications of membranes for selecting for instance, for filtering for instance base. In addition is the equipment that we have at the different places like inkjet printers, printers that we are using, this is the AAG printer and we also have the equipment for the characterization like profilometry, bending test, AFM, 4 point probe and one of the center pictures what you see here is the need that is the requirements necessary to develop inks, the combination of requirements that are needed in order to get at the end an optimized printing result and the instrumentation that we have together with the characterization enables us to do the ink development for customers who are interested in also upscaling production with inkjet printing or other printing techniques. So you have the cutting edge best printed electronics like research facility? I think, I mean it's always nice to have something more but we have facilities for doing all the processes that are necessary to produce this type of electronic devices and also the characterization facilities for those and for us, these are the cutting edge facilities, yes. What kind of discussions do you have here at the nanotechnology conference? People want to work with you in all kinds of stuff? I have to think the moment before I talk into the camera. To come to nanotechnology for us it's important to meet people from the same area as we are working on for instance we had a long cooperation with the nanotechnology lab here in Kessaloniki and there is a close exchange of information this time that's an important task we have but it's also important to meet projects partners that we already have or maybe future project partners in the field of printing but also in the field of material development.
