We are accustomed to the use of electricity in every day life, this is based on the flow of electrons through materials which have a high conductivity such as metals. At low temperatures the laws of quantum mechanics prevail and now an electron does not behave as a particle but rather as a wave, which reflects the probability of finding an electron in a particular place. An entirely new range of phenomena flow from this change in the physics and this is most pronounced in very small devices, called nanostructures. The purpose of this grant is to enable the most advanced nanostructures to be fabricated and new physical phenomena to be sought in them. In addition to the new physics that will be found, new methods of transmitting and handling data will emerge, which will be of great benefit to both existing and future industries yet to be born.

我们习惯于在日常生活中使用电，这是基于电子通过金属等高导电性材料的流动。在低温下，量子力学定律占主导地位，现在电子不再表现为粒子，而是表现为波，这反映了在特定位置找到电子的概率。这种物理变化产生了一系列全新的现象，这在称为纳米结构的非常小的设备中最为明显。这笔资助的目的是制造最先进的纳米结构并在其中寻找新的物理现象。除了将发现的新物理之外，还将出现传输和处理数据的新方法，这将对现有和未来即将诞生的行业带来巨大好处。
