Over the past three years, Dr Yu has received close to S$3.5m worth of research grants. In 2008, his team won the Nanyang Award for Research and Innovation, a prestigious NTU award presented in recognition of their outstanding research achievements.
Despite receiving this latest accolade, Dr Yu is clearly not resting on his laurels. He is currently working on two research projects fabricating high-quality and large-yield metal oxide nanostructures, and tailoring the electronic structure of graphene for nanoelectronic applications.
"For the metal oxide nanostructures, my team and I will focus on two aspects control and novelty. We want to control the quality and assembly of nanostructures by making use of new methods, models and systems," he said.
"As for graphene, we are already able to grow large pieces of it, which is the very first requirement for practical applications. We have also demonstrated two effective strategies to tailor the electronic structure of graphene. We will be studying more methods to optimise these parameters," added Dr Yu.
"Our work could possibly have useful applications for nanoelectronics, photonics and phononics," said Dr Yu. "For example, using graphene, we could possibly build an ultrafast computer where the electron could move about 200 times faster than silicon, which is currently used in computer chips," he explained. "Another application could be using graphene as electrodes in flexible display screens or solar cells because of its high conductivity and transparency."
Driven by a burning desire to see the world rely more on green energy, Dr Yu hopes his research efforts will result in the harvesting of green energy such as developing ultracapacitors, super-Lithium-ion batteries and wide-range solar cells.
