Silicon emission technologies based nanocrystals

项目摘要

The global semiconductor market has a value of around $1trillion, over 90% of which is silicon based. In many senses silicon has driven the growth in the world economy for the last 40 years and has had an unparalleled cultural impact. Given the current level of commitment to silicon fabrication and its integration with other systems in terms of intellectual investment and foundry cost this is unlikely to change for the foreseeable future. Silicon is used in almost all electronic circuitry. However, there is one area of electronics that, at the moment, silicon cannnot be used to fill; that is in the emission of light. Silicon cannot normally emit light, but nearly all telecommunications and internet data transfer is currently done using light transmitted down fibre optics. So in everyones home signals are encoded by silicon and transmitted down wires to a station where other (expensive) components combine these signals and send light down fibres. If cheap silicon light emitters were available, the fibre optics could be brought into everyones homes and the data rate into and out of our homes would increase enormously. Also the connection between chips on circuit boards and even within chips could be performed using light instead of electricity. The applicants intend to form a consortium in the UK and to collaborate with international research groups to make silicon emit light using tiny clumps of silicon, called nanocrystals;. These nanocrystals can emit light in the visible and can be made to emit in the infrared by adding erbium atoms to them. A number of techniques available in Manchester, London and Guildford will be applied to such silicon chips to understand the light emission and to try to make silicon chips that emit light when electricity is passed through them. This will create a versatile silicon optical platform with applications in telecommunications, solar energy and secure communications. This technology would be commercialised by the applicants using a high tech start-up commpany.

全球半导体市场的价值约为1万亿美元，其中90%以上是硅基半导体。在许多意义上，硅在过去40年里推动了世界经济的增长，并产生了无与伦比的文化影响。考虑到目前对硅制造的承诺水平，以及它与其他系统在智力投资和铸造成本方面的集成，在可预见的未来，这种情况不太可能改变。几乎所有的电子线路都使用硅。然而，有一个电子领域目前还不能用硅来填充，那就是发光。硅通常不能发光，但目前几乎所有的电信和互联网数据传输都是通过光纤传输的光完成的。因此，在每个家庭中，信号都是由硅编码的，然后沿着电线传输到一个站点，在那里其他(昂贵的)组件将这些信号组合在一起，并将光沿着光纤发送。如果有廉价的硅光发射器，光纤就可以进入每个家庭，进出我们家庭的数据速率将大大提高。此外，电路板上的芯片之间甚至芯片内部的连接也可以使用光而不是电来实现。申请者打算在英国组成一个财团，并与国际研究组织合作，利用微小的硅团(称为纳米晶体)使硅发光。这些纳米晶体可以在可见光下发光，并可以通过向它们添加Er原子来使其在红外线发射。曼彻斯特、伦敦和吉尔福德提供的许多技术将被应用到这种硅芯片上，以了解光发射，并试图制造出在电流通过时发光的硅芯片。这将创造一个多功能的硅光平台，应用于电信、太阳能和安全通信。申请者将使用一家高科技初创公司将这项技术商业化。
