Superlatticed or “striped" nanorods – crystalline materials only a few molecules in thickness and made up of two or more semiconductors – are highly valued for their potential to serve in a variety of nanodevices, including transistors, biochemical sensors and light-emitting diodes (LEDs). Until now the potential of superlatticed nanorods has been limited by the relatively expensive and exacting process required to make them. That paradigm may be shifting.
