The National Laboratory of Solid State Microstructures (NLSSM) was founded in 1984, among the first batch of state key laboratories founded in China. The laboratory is operated by Nanjing University. As a multidisciplinary science and engineering research center, the goals of NLSSM are to design and fabricate new artificial microstructured materials via designing and tailoring the energy band structures in reciprocal space, find out new macroscopic and microscopic quantum effects and principles, develop new theories and methodology based on quantum physics, and endeavor to meet the scientific challenges and technological requirements encountered in the post-Moore era and the post-petroleum era. Prof. Dingyu Xing is the director of academic committee and Prof. Mu Wang is the director of the laboratory. There are 48 staff members in NLSSM, including 8 Academicians of CAS, 15 professors awarded by the Yangtze River Scholar Plan, 15 professors receiving the National Science Fund for Distinguished Young Scholars. In 1994 the first paper published in Nature of the laboratory, which is about the mechanism of the interfacial growth, is a breakthrough for publishing papers in the highest level academic journals. Later, a set of results about dielectric superlattice were published in high level international academic journals, including three papers in Science. In all the assessment for the state key laboratories, NLSSM was always assessed to be an excellent laboratory and was ranked first in the group of mathematics and physics in 2000. The journal of Nature assessed that NLSSM was one of the institutes in the pacific rim of Asia excluding Japan approaching world-class standards in research in 1997 [Nature 389, 113 (1997)]. As one of the major research centers in condensed matter physics in China, research projects currently being carried out in NLSSM cover many important branches in artificial microstructure physics, quantum physics and the associated electronics, nanostructure properties and devices, soft condensed matter physics and computational physics. These researches are funded by several national, provincial and ministerial research fund, including 6 projects of National Basic Research Program of China (973 program), 15 sub-projects of 973 program, 4 projects of National High-tech R&D Program of China, 7 projects of Key Program of National Natural Science Foundation of China, etc., in NLSSM. The NLSSM members have won the First Class Prized of National Natural Science Award for one time and the Second Class Prized of National Natural Science Award for 6 times since 2002. Currently, 27 principal investigators are leading their groups and working mainly in the Cyrus Tang Building with a total laboratory space of over 20,000 m2. The major state-of-the-art equipments in NLSSM include field-emission transmission electron microscope (Philips F20); spin-resolved ultrahigh vacuum scanning tunneling microscopy (Omicron); field-emission scanning electronic microscope (LEO 1530VP); solid state nuclear magnetic resonance system (Bruker Arance 300); and superconducting quantum interference device (SQUID) (MPMSXL-7). In addition, there are numerous thin film/bulk material fabrication facilities, as well as structural and spectrum characterization facilities. An advanced nanofabrication center, equipped with electron beam lithography system (Raith e-Line) and focusing ion-beam fabrication facility (Philips FB201), has been established, which will serve the needs for fabrications of nano/micro sized structures. Moreover, the supporting facilities include super-computer system and low temperature workshop for providing liquid helium and liquid nitrogen. In the period of 2005-2009, the Laboratory has published 1858 peer-reviewed research papers, among which there are 39 in Physical Review Letters, 209 in Physical Review series, and 178 in Applied Physics Letters. During this period the number of authorized patents reaches 90, in addition to 86 new applications. NLSSM is a public platform for international exchanges and cooperation. The Laboratory has accommodated many internship students, postdoctoral research associates and visitors, from domestic and abroad. The Laboratory has collaboration agreements with research institutes and universities in US, Japan, France, Germany, Italy, etc. Many joint research papers have been published in Science, Nature Photonics, Advanced Materials, and Physical Review Letters. The Laboratory sincerely welcomes international cooperation in areas of material design, quantum physics, nanooptics and plasmonics, clean energy and environment-related studies.
