Nanomaterials at Interfaces: Wet Chemical Routes for Size, Shape and Orientation Controlled Nanomaterials

Wet chemical routes for synthesis of semiconductor nanostructures and thin films are straightforward, cost-effective and can result in high quality nanomaterials with precise size and shape control. Two synthetic methods will be presented, both in which interfacial processes play a major role. The first method, chemical bath deposition, offers a simple and versatile route for producing high quality semiconductor thin films directly onto single crystal substrates without the use of organic ligand molecules. A wide range of microstructures is obtained, from nanocrystalline films to monocrystalline films with a well-defined orientation with the substrate. The second technique will highlight highly uniform nanoparticles capped with alkylamine surfactants, and will focus on the role of the organic surfactants in controlling their shape and assembly into 2D and 3D super-structures.
Prof. Yuval Golan is a professor of Materials Engineering and holder of the Eric Samson Chair of Advanced Materials and Processing at Ben Gurion University of the Negev, Beer-Sheva, Israel. He earned his PhD from the Weizmann Institute in 1996 and was a Fulbright postgraduate researcher at the Materials Research Laboratory, UC Santa Barbara until fall 1999, when he joined the faculty of BGU. In 2010 he was promoted to full professor in the Department of Materials Engineering and appointed as permanent director of the Ilse Katz Institute for Nanoscale Science and Technology at BGU. Dr Golan is active in the area of nanomaterials and thin films, has published 120 peer reviewed publications, many of them in top notch journals, and supervised over 25 research students and postdocs. Since 2016, Dr Golan has been also serving as Chairman of Graduate Studies at the BGU Dept. of Materials Engineering.
