Definition

In nanotechnology, any fabrication process naturally introduces disorder and randomness at the nanoscale. Disorder is typically unwanted in applications, as it is associated with unpredictable degrees of freedom that are difficult to control. However, it can be demonstrated that disorder supports fascinating and counterintuitive phenomena, which can be harnessed at the nanoscale for the realization of specific functionalities.

Introduction

It is a common perception that the presence of disorder influences negatively the properties of a physical system. Nevertheless, there are several cases in which disorder plays a positive role and can be exploited to develop novel applications. In general, the introduction of disorder significantly increases the complexity of the system under examination, but, as is often seen in nature, an increase in ...
