In partially depleted SOI, the top layer is between 50- to 90-nm thick. Silicon under the channel is partially depleted of mobile charge.
在部分耗尽型SOI结构中,SOI中顶层硅层的厚度为50-90nm,因此沟道下方的硅层中仅有部分被耗尽层占据,由此可导致电荷在耗尽层以下的电中性区域中累积,造成所谓的浮体效应。
Climate change and the depleted ozone layer are among the starkest examples.
气候变化和臭氧层耗减就是其中最明显的例子。
Although CFCs have been banned, the ozone layer is still being depleted from gases released many years ago, and holes exist above both poles.
