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.

Dr Zheng is currently appointed as a Postdoc fellow at New York University under the supervision of Prof. Elisa Riedo. Dr Zheng’s research interests lie in the nano-photonics of low-dimensional materials for both functional photonic and electronic applications.


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.
