futuristic applications. In this light, novel grating coupled hyperbolic metamaterial configuration
enhances the spontaneous emission rate of dye molecules by exploiting the unique property of a hyper
grating outcoupling and extracting the non-radiative plasmonic modes.

Optoelectronic thin films for flexible electronics
Dr. Weijie Song, Chinese Academy of Sciences, China, November 25
th
Dr. Weijie Song is currently a research professor in the Ningbo Institute of Material Technology and
Engineering, Chinese Academy of Sciences, People's Republic of China. His talk

explored the development of flexible electronics, which has contributed significantly
to the demand for optoelectronic films. He first introduced some basics of flexible
optoelectronic thin films and then further described the research progress of our

research team in flexible transparent conductive thin films. He also discussed his
team's transparent conductive thin films based on silver nanowires and ultrathin
metals. Finally, he showed model devices prepared based on the above films, new

information and energy fields applications, and mass production techniques for the relevant thin films.
Functional electronic applications based on heterogeneously integrated complex

oxide films
Dr. Xiao Renshaw Wang, Nanyang Technological University, Singapore, December 17

Dr. Xiao Renshaw Wang is currently an Assistant Professor at the School of Physical

and Mathematical Sciences and School of Electrical and Electronic Engineering at
Nanyang Technological University, Singapore. He discussed heterogeneously-
integrated complex oxide films. Dr. Wang showed what may happen when different
layers of materials and functionalities are unrestrictedly stacked at an atomic scale. He

described artificially integrating the naturally incompatible atomic structures,
crystallographic orientations, and physical functionalities. The interplays at the
interfaces induce unexpected functionalities, which is beneficial to future electronics in manipulation,

functionalization, and utilization. However, realizing unrestricted heterogeneous integration and their
electronic applications is highly challenging because of the technical restrictions of fabrication and the
unwanted reduction of interface quality. The challenges are particularly severe in the heterogeneous

integration of oxides with either other emerging materials or existing Si technologies because of the
incompatible growth dynamics and large lattice mismatch.
