1 Introduction
A strong focus on materials sciences and novel material systems also exists in
Hangzhou, China. The ZJU hosts two State Key Laboratories, one of them the State
Key Laboratory of Silicon Materials (the other one on Modern Optical Instrumentation), and many groups in physics, chemistry and other departments researching in
this wider field of functional nanomaterials sciences. Thereby, the ZJU contributes
significantly among other Chinese top universities to the developments in this field.
Indeed, the Chinese research landscape contains numerous State Key Laboratories,
as well as nanoscience, information-technology-related or materials science research
centers which are strongly committed to research on these subjects.
1.2.1 Novel Material Systems
Obviously, 2D materials and their heterostructures received considerable attention in
recent years on various conferences and workshops, whereas other highly-attractive
conventional and novel material systems are also worth mentioning, such as silicon
and III/V semiconductors on the one side and perovskites or materials with special
topological properties (e.g. topological insulators) on the other, respectively. Nevertheless, not all of the discovered and tailored material systems that were also subject
of the FNMS2018 symposium may end up in commercial devices in the near future,
although their long-term impact may be heavily anticipated at this stage.
With the vision of harnessing the remarkable properties of 2D materials, Y. Chai
from the Hong Kong Polytechnic University summarised that as the semiconductor
industry enters into the post-Moore era, the “heterogeneous integration” becomes a
trend. He and his co-workers considered the introduction of 2D materials for future
interconnect and transistor applications.
Naturally, the controlled synthesis of 2D materials, such as graphene and MoS 2
(a prominent representative of the TMDC class of 2D semiconductors) remains of
great importance, in order to enable electronic and optoelectronic applications of
2D layered and non-layered metal–chalcogenides semiconductors, as well as their
heterostructures. This was for instance addressed by Beijing’s J. He from the National
Center for Nanoscience and Technology, and by M. Xu from the State Key Laboratory
of Silicon Materials and ZJU, who highlighted uniform graphene growth with eyes
towards the application of 2D materials to solar cells, particularly flexible organic
solar cells with graphene-based transparent electrodes.
Intriguing findings related to 2D materials properties also rely on their particular
crystal structure. New Dirac fermion states in 2D puckered group-Va elements layers
were recently found by Y. Lu and co-workers from the ZJU in Hangzhou. In addition, spontaneous electric polarisation and ferroelectricity in 2D elemental Group-V
(As, Sb, and Bi) monolayers with the puckered lattice structure similar to that of
phosphorene was highlighted by him.
Towards plasmonics with 2D materials, the interaction between nanoscale metallic
entities and 2D materials such as graphene or MoS 2 can be modified in a controlled
way and these effects can be probed by Raman spectroscopy, P.J. Klar from the
Justus-Liebig-Universität Giessen reported.
