ABSTRACTAlthough heteroepitaxy of lattice-matched and lattice-mismatched materials leading to artificially structured materials has resulted in impressive performance in various electronics devices, material combinations are usually limited by lattice matching constraints. A new concept for fabricating material systems using the atomically abrupt and low dimensional nature of layered materials, called van der Waals epitaxy (VDWE), has been developed. GaSe (Eg = 2.1 eV) has been deposited on the three dimensional surface of GaAs (111) using a molecular beam deposition system. GaSe was evaporated from a single Knudsen source, impinging on a heated substrate. Even with a lattice mismatch of 6% between the substrate and the growing film, good quality single crystal films were grown as determined by RHEED. The films have further been analyzed using a complementary combination of XPS and X-ray reflectivity.

With the rise of nanoscience and nanotechnologies, especially the continuous deepening of research on low-dimensional materials and structures, various kinds of light-emitting devices based on nanometer-structured materials are gradually becoming the natural candidates for the next generation of advanced optoelectronic devices with improved performance through engineering their interface/surface properties. As dimensions of light-emitting devices are scaled down to the nanoscale, the plentitude of their surface/interface properties is one of the key factors for their dominating device performance. In this paper, firstly, the generation, classification, and influence of surface/interface states on nanometer optical devices will be given theoretically. Secondly, the relationship between the surface/interface properties and light-emitting diode device performance will be investigated, and the related physical mechanisms will be revealed by introducing classic examples. Especially, how to improve the performance of light-emitting diodes by using factors such as the surface/interface purification, quantum dots (QDs)-emitting layer, surface ligands, optimization of device architecture, and so on will be summarized. Finally, we explore the main influencing actors of research breakthroughs related to the surface/interface properties on the current and future applications for nanostructured light-emitting devices.

There is great current interest in layered anisotropic materials. Much of the interesi relates to the possibility of an approximate decoupling of 3-dimensional (3D) behavioi into ID properties perpendicular to the layer planes and 2D properties associated with the layer planes. Since this decoupling in layered materials is enhanced by intercalation, much attention has been given to intercalation compounds in recenl years as a means to study interesting questions of low dimensional physics. Since many deliberately structured materials also are prepared in layered sequences, there are many close connections between the properties of intercalated layered materials and deliberately structured materials. This article will focus on several important connections between intercalated layered materials and multilayered superlattice structures prepared by molecular beam epitaxy (MBE) and metalorganic chemical vapor deposition (MOCVD).Interest in intercalation compounds has led to three lively MRS symposia on this topic (Fall 1982, Fall 1984, Fall 1986) and a number of summer schools and workshops, one of which was held in July 1986 at Erice, Sicily, under the auspices of NATO and the European Physical Society. The published lecture notes1 from this summer school provide a useful introduction and reference for students and others interested in this field.
