薄膜,在现代科学技术中占据着重要地位,它是不少研究领域和技术领域所共同关心的课题.近十几年来,薄膜科学与现代固体物理的一个前沿——表面物理互相促进,薄膜技术的应用得到了迅速的发展. 为了说明薄膜的重要性,先让我们看一个例子.1946年,世界上制成的第一台数字电子计算机的体积约90立方米,重达30吨,耗电140千瓦,运算速度为5000次/秒(加法).三十年后,用几块大规模集成电路装配成的微处理机,功能与上述数字电子计算机相当,体积仅0.003立方米,为前者的三十万分之一,
Film occupies an important position in modern science and technology and it is a common concern in many fields of research and technology.In the past ten years, one of the frontiers of thin film science and modern solid physics - surface physics mutually promote, thin film technology To illustrate the importance of the film, let us look at an example .1946, the world’s first digital computer made of about 90 cubic meters in volume, weighing 30 tons, the power consumption 140 kilowatts, the computing speed of 5000 times / second (addition). Thirty years later, with a few large integrated circuits assembled into a microprocessor, the function of the digital computer, the volume of only 0.003 cubic meters, the former One in three hundred thousandth,
