We had the pleasure to interview Dr. Athanasios Dimoulas in the past and it seems that this interview is as interesting as the previous one. Athanasios Dimoulas is the head of Epitaxy and the Surface Science Laboratory at NCSR “Demokritos” and he gives us an update with the latest developments of new novel materials in nanoelectronics. The explosion of big data and IoT has resulted in a great need for energy efficient smart devices. Dr Dimoulas shares some of the problems and insights with their research on these hard to develop materials like graphene, Weyl fermions and others. He then reveals how crystals could simulate a “particle accelerator” and test some of the fundamental principles and assumptions in high energy, elementary particle physics and cosmology. This could result in discovering new interesting properties and being able to integrate them faster in electronic devices, capacitors and transistors, in the hope of impacting emerging Quantum Technologies.
