以半导体为题写一篇600字的作文

半导体（ semiconductor），指常温下导电性能介于导体（conductor）与绝缘体（insulator）之间的材料。半导体在收音机、电视机以及测温上有着广泛的应用。如二极管就是采用半导体制作的器件。半导体是指一种导电性可受控制，范围可从绝缘体至导体之间的材料。无论从科技或是经济发展的角度来看，半导体的重要性都是非常巨大的。今日大部分的电子产品，如计算机、移动电话或是数字录音机当中的核心单元都和半导体有着极为密切的关连。常见的半导体材料有硅、锗、砷化镓等，而硅更是各种半导体材料中，在商业应用上最具有影响力的一种。

钻石可能成为理想的半导体

Along with being a "girl's best friend," diamonds also have remarkable1properties that could make them ideal semiconductors3. This is welcome news for electronicssemiconductors are needed to meet the rising demand for more efficient electronics that deliver and convert power. The thirst for electronics is unlikely to cease and almost every appliance or device requires a suite4of electronics that transfer, convert and control power. Now, researchers have taken an important step toward that technology with a new way to dope single crystals of diamonds, a crucial process for building electronic devices.

"We need the devices to manipulate the power in the way that we want," said Zhengqiang (Jack) Ma, an electrical and computer engineering professor at the University of Wisconsin-Madison. He and his colleagues describe their new method in the Journal of Applied5 Physics, from AIP Publishing.
