Dr. Lisheng Wang was a Postdoctoral Research Associate in our lab from December 2008 to September 2012. He received his PhD degree in Materials Science and Engineering at State University of New York at Stony Brook in 2008, prior to which he completed his bachelor’s and master’s degrees in Materials Science and Engineering at Tsinghua University in 2003 and 2005, respectively.
Dr. Wang’s research here was focused on fabrication of nanostructured materials and applications of these materials in electronic devices. As an example, he has been successful in fabricating ZnO nanowires on various platforms as building blocks of various types of devices, including piezoelectric converters, LEDs and field emission displays, etc. Dr. Wang also participated in applications of inkjet printing technology in different areas, e.g. plant studies and printable devices, etc.
Besides his research work, Dr. Wang was also responsible for managing day-to-day operations of the lab and coordinating team activities of an NSERC Strategic Project.
Dr. Wang left our group in September 2012. He is currently Product Test Engineer in Cooledge Lighting Inc.
Abstract: Thin films composed of self-supporting ZnO nanowire arrays are fabricated via a hydrothermal approach without the presence of any substrates. The films can be transferred and bonded to an arbitrary substrate for device applications. As a demonstration, a piezoelectric converter is made which is able to generate electric charge under compressive forces.

Abstract: To apply inkjet micropatterning to plant studies, we have successfully delivered landmarks on ivy leaf surfaces and achieved high-resolution, two-dimensional monitoring of leaf expansion at different growing stages. The measurement is capable of reliably identifying the fine scale changes during plant growth. As well as delivering landmarks, this technology may be used to deliver microscale targeted biological components such as growth hormones, and possibly be used to pattern sensors directly on the leaves.
