任何一门科学技术都有一个逐渐的成长过程，并且与它的前一代的同门科学技术既有继承，又有其本质上与之区别的特点。微电子学对于其前一代的传统电子学是如此，纳电子学与微电子学也是如此。纳电子器件是指尺寸为纳米级，但其工作机理有异于MOSFET，且其性能有可能大幅度提高 Any science and technology has a gradual process of growth and has the same characteristics as its predecessors, the same science and technology of their own. Microelectronics is true for its predecessors of traditional electronics, as well as nanoelectronics and microelectronics. Nanoelectronics refers to the size of nano-scale, but its working mechanism is different from the MOSFET, and its performance is likely to significantly improve
