Venue: Academic Conference Center, IOS, CAS 
Abstract: In this talk, I will discuss the recent academic and industrial development of van der Waals material based devices for advanced logic, memory and computing technologies. Two-dimensional (2D) transition metal dichalcogenides materials are promising candidates for advanced logic transistor applications. It however still faces difficulties towards practical commercialization due to challenges in device contact resistance, gate dielectric technology, integration process development, as well as its reliability and yield. In the first part of the talk, I will discuss our recent work in addressing some of these issues. Moreover, the unique physical properties of 2D materials also offer opportunities for developing novel memory and computing device technologies that can result in substantial performance improvement over traditional semiconductor devices as well as enabling new device and circuit functionalities difficult to achieve using conventional technologies. In the second part of the talk, I will discuss our work in developing such new semiconductor devices including 2D material based ferroelectric tunneling junction memory and stochastic computing devices for efficiently solving combinatorial optimization problems. I will conclude with remarks on how van der Waals material devices are expected to benefit the next-generation electronics systems and the remaining roadblocks that need to be overcome.
