Transport at Nanoscale Interfaces Laboratory

Abstract

Carbon-based materials have generated a wealth of interest in recent years, both on the fundamental side as well as on the technological side. The lecture will provide a broad insight into nanoscale carbon-based materials, from their fundamental opto-electronic properties to their implementation in practical devices. We will first discuss the electronic properties of carbon-based materials, focusing on low-dimensionality systems, starting from short molecules that can be seen as 0D quantum dots, to graphene, a 2D material with remarkable mechanical, electrical and optical properties. The experimental techniques to fabricate and electronically characterize such systems will then be addressed and their electronic transport properties discussed. Finally, we will extend the discussion to practical devices such as ion-sensing field-effect transistors.

May 03, Welcome to Patrik ! =)

Dr. Patrik Rohner joins the lab to establish electrohydrodynamic nanoprinting @EMPA in a collaborative effort of EMPA and ETHZ (Prof. Maksym Kovalenko).

I am a Swiss nanofabrication engineer. I studied Mechanical Engineering at ETH Zurich from BSc to PhD. During my PhD, I built nanoscale gold walls and fluorescent nanocrystal assemblies by electrohydrodynamic (EHD) printing, a unique fabrication technology developed in the lab of Prof. Dimos Poulikakos. 
At EMPA, I will set up a versatile EHD nanoprinting system to share this technology to a broader user group, enabling device prototyping at the Transport at Nanoscale Interfaces Laboratory with Ivan Shorubalko, supported by printing materials made at the lab of Prof. Maksym Kovalenko (ETHZ D-CHAB and EMPA).
