Presentation: 30 min
Q&A: 15 min
Two-dimensional semiconductors, such as molybdenum disulfide (MoS2), exhibit a variety of properties that could be useful in the development of novel electronic devices. However, nanopatterning metal electrodes on such atomic layers, which is typically achieved using electron beam lithography, is currently problematic, leading to non-ohmic contacts and high Schottky barriers.
In this talk, I will show that thermal scanning probe lithography can be used to fabricate high-quality metal contacts on 2D materials, offering excellent performance for 2D electronic devices.
Elisa Riedo graduated summa cum laude in Physics at the University of Milano, and obtained a Ph.D. in Physics in 2000 with a joint thesis between the University of Milano, and the European Synchrotron Research Facility (ESRF) in Grenoble, France. She then worked as postdoctoral fellow at the Ecole Polytechnic Federale de Lausanne (EPFL) in Switzerland. Riedo was a Professor of Physics at the Georgia Institute of Technology from 2003 to 2015. She is particularly well known for her pioneering work in thermochemical scanning probe lithography (SPL), a technique used to create nanoscale chemical patterns with applications in biomedicine, nanoelectronics, and magnetic materials. She has also made fundamental contributions in nano-mechanics, 2D materials, and nano-confined water, relevant in all living systems. She is widely published, has received multiple grants from the National Science Foundation and the Department of Energy, and is a Fellow of the American Physical Society.
Webinar Series description
The “NanoFrazor Technology” webinars will explain the main features and limitations of NanoFrazor lithography. They will be hosted by the key experts of our R&D teams. You will learn how our technology works, and where and why it is superior or inferior to conventional nanolithography techniques. We will also share the results and insights of our ongoing development projects.
The “NanoFrazor Applications” series will show examples from different application fields, where the NanoFrazor was used to fabricate unique nanopatterns and devices. The guest speakers - scientists who actively use NanoFrazor - will talk about their work and recent results.
The “NanoFrazor Sales” webinars will focus on NanoFrazor products. We will talk about hardware components and software features of the NanoFrazor systems. We will also cover the cost-of-ownership and how to receive a quick return on investment. Finally, we will also offer a dedicated webinar where you will learn about the various funding options for NanoFrazor systems and how to maximize your chances to get your funding proposal accepted.
Test yourself and win! After each webinar, you can test what you have learned in a short multiple-choice questions challenge. With 10 or more successful tests, you will receive a small prize and a unique Nanofabrication Guru certificate.
