50 DESIGN007 MAGAZINE I MARCH 2019 Shaughnessy: And what is your original degree? Martinez: I studied industrial engineering in Spain, and I did my master's thesis at FH Joan- neum, which is how I got to know the research center. Shaughnessy: And I'm guessing you use Alti- um tools? Martinez: Yes. Altium is very important to us. We do high-powered converters. For example, we need to control the clearance and printed requirements in these power devices. In Alti- um, having a set of design rules with every- thing you can control is very useful for us. My whole work is based on Altium. Shaughnessy: What classes are you teaching at the university? Martinez: I'm teaching practical courses on Alti- um, actually. I'm teaching how to design PCB cir- cuits as well as some courses and labs on power electronics, including semiconductor packaging. Shaughnessy: How did you get into wanting to do this as a career? Were you just always inter- ested in electronics when you were growing up? Martinez: My studies in industrial engineering were very general, and I got the feeling that ev- erything had already been invented there. But in electronics, everything is new and develop- ing very fast. We have high-speed design and high-powered design, and I feel like there's so much I can do in this field. That's also how I got to know Altium. Altium's also develop- ing very fast, and it's the perfect tool for doing what I like, which is hardware design. Shaughnessy: Do you have any advice for young people who are just getting into PCB de- sign or design engineering? Martinez: For young designers, I would recom- mend reading all of the line documentation for Altium or whatever tool you use. You get the feeling for how this works and what you can do with the tool. That's what I did. It's a very good way to start. And go to conferences like this. Shaughnessy: Do you attend a lot of events like this? Martinez: This is the second year I've come to this conference in Munich, and I have the feel- ing that there is nothing similar to it in Europe. At this show, you can get to know designers with the same interests and experiences, and you can share what you have learned. You can get to know different points of view on hard- ware design. Shaughnessy: Thanks for speaking with me, Pablo. Good luck with your studies. We need more professors who can teach PCB design. Martinez: Thank you, Andy. Maybe I will see you again. DESIGN007 Organic semiconductors enable the fabrication of large- scale printed and mechanically flexible electronic applica- tions. To break into further market segments, improvements in performance are still needed. Doping is the answer. Researchers from the Dresden Integrated Center for Ap- plied Physics and Photonic Materials (IAPP) and the Cen- ter for Advancing Electronics Dresden (cfaed) at TU Dres- den in cooperation with Stanford University and the Insti- tute for Molecular Science in Okazaki have identified key parameters that influence electrical conductivity in doped organic conductors. The combination of experimental investigations and simulations has revealed that introducing dopant mole - cules into organic semiconductors creates complexes of two oppositely charged molecules.
