In the last decades, to obtain increasingly high-performance devices, both in sense of frequency and density of logic elements in a single chip, a continuous scaling of electronic technology has been performed following Moore's law. Nowadays it is quite physically impossible to continue the scaling using a standard structure based on metal oxide and semiconductor due to atomic scale size. For this reason, some alternatives must be found in order to continue with the technological progress. In the last decade, the concept of Beyond-CMOS was born. It refers to the discovery and the development of new technologies, no more CMOS based, that can overcome the mentioned problems.
