Invited Talk

Description

Two-dimensional (2D) layered materials are explored for next-generation hybrid devices such as micro- and nano-electro-mechanical systems (MEMS/NEMS), sensors and electron emitters. This talk discusses hybrid devices of 2D materials integrated with silicon by scalable techniques. The vapour phase grown 2D materials typically deviate from perfect crystallinity, exhibiting domain sizes ranging from a few nano- to several micrometers. Thus, these structural imperfections remain to be of the mayor challenges for 2D materials-based devices, however, also bear new functionalities, compromising opportunities for novel devices functionalities. The chemical and morphological properties of the layers and functional stacks are characterized using a range of complementary techniques, including Raman X-ray photoelectron spectroscopy (XPS). Finally, the electrical performance of devices based on these not-so-perfect 2D materials will be discussed.
