For the first time, scientists have managed to create sheets of gold only a single atom layer thick. According to the researchers from LiU this has given the gold new properties that can make it suitable for use in various applications.

A new method to fit together layers of semiconductors as thin as a few nanometres has resulted in not only a scientific discovery but also a new type of transistor for high-power electronic devices. The result, published in Applied Physics Letters.

X-ray photoelectron spectroscopy (XPS) is often used to determine the chemical composition of materials. It is accepted as a standard method in materials science. Researchers at LiU, however, have shown that the method is often used erroneously.
