在晶体学水平上固有的降维对低维材料的电子特性的影响可能是巨大的，导致结构和电子的不稳定性，包括高温下的超低温、电荷密度波和定位，这些都继续吸引着广泛的兴趣。层状过渡金属二硫族化合物多年来一直受到人们的关注，部分原因是由于一些人所显示的电荷密度波效应和通过插层修饰其性质的可控方式，而基于二硫族化合物异质结构和量子阱的外延生长技术的发展开辟了有前途的领域。高温超导氧化物的发现，以及聚合物材料也可以以可控的方式用于各种光电应用的认识，进一步激发了人们对结构尺寸影响的兴趣。因此，将涉及一系列不同材料的近期研究结合在一起似乎是及时的，这些材料具有低维度的一些共同特征。本书的目标读者是对所讨论的特定材料有专业兴趣的研究人员，但他们也可能希望研究在不同系统中观察到的相关现象，以及对电子特性和低维现象有广泛兴趣的更一般的固态听众。由于空间的限制，我们必须对特定的材料进行选择，尽管我们已经设法包括了聚合物半导体、超导氧化物、青铜和层状硫属化合物等不同的材料。
The effect of reduced dimensionality, inherent at the crystallographic level, on the electronic properties of low dimensional materials can be dramatic, leading to structural and electronic instabilities—including supercond-tivity at high temperatures, charge density waves, and localisation—which continue to attract widespread interest. The layered transition metal dichalcogenides have engaged attention for many years, partly arising from the charge density wave effects which some show and the controlled way in which their properties can be modified by intercalation, while the development of epitaxial growth techniques has opened up promising areas based on dichalcogenide heterostructures and quantum wells. The discovery of high-temperature superconducting oxides, and the realisation that polymeric materials too can be exploited in a controlled way for various opto-electronic applications, have further sti-lated interest in the effects of structural dimensionality. It seems timely therefore to draw together some strands of recent research involving a range of disparate materials which share some common char-teristics of low dimensionality. This resulting volume is aimed at researchers with specialist interests in the particular materials discussed but who may also wish to examine the related phenomena observed in different systems, and at a more general solid state audience with broad interests in electronic properties and low dimensional phenomena. Space limitations have required us to be selective as regards particular materials, though we have managed to include those as dissimilar as polymeric semiconductors, superconducting oxides, bronzes and layered chalcogenides.
