Abstract

In this webinar I will mainly explain and discuss the fabrication methods as well as the scientific results of the following two papers:

Zheng et al., “Patterning metal contacts on monolayer MoS2 with vanishing Schottky barriers using thermal nanolithography” (Nature Electronics 2019)

Zheng et al., “Spatial defects nanoengineering for bipolar conductivity in MoS2 Two-dimensional semiconductors” (Nature Communications 2020)

 

Speaker's Bio:

Dr. Xiaorui (Ray) Zheng joined Westlake University in 2020 as an Assistant Professor and started the Alien Lab (Advanced Lithography for Opto-Electronic Nanochips Lab). After his MSc in Condensed Matter Physics at the Chinese Academy of Science, he obtained a PhD at the Centre for Micro-Photonics at Swinburne University of Technology. He was postdoc research fellow at University of California, San Diego and at CUNY and NYU in the group of Prof. Elisa Riedo. In the latter group, he used the NanoFrazor to achieve several breakthrough results with the fabrication of 2D material devices. His research at Westlake University will continue in this direction where he has plenty of ideas on how to utilize the NanoFrazor technology for novel and improved 2D material devices.

 

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.
