What is it about?
Semiconductor nanowires are promising for future optoelectronics, as lasers, LEDs and sensors because their size is on the order of the wavelength of light. This leads to strong interactions, however, small changes in the nanowire size or shape can lead to big changes in their performance. In this review, we discuss how these variations come about, how we can measure them, and what they can tell us.

Why is it important?
While nanowires have been demonstrated in applications for many years, it remains unusual for them to be used in industrial applications due to low yield. In this work, we review disorder and yield in a wide variety of nanowire materials, and discuss ways to properly measure this.
Perspectives
This work is a manifesto for the work of my reseach group, who are focussing on wire-to-wire variation. It is a review at the start of our research project, and we plan to address the issues raised during the next few years.
