There is a lot of buzz about the potential for using semiconductor nanowires in next generation electronic, optoelectronic, and biosensor applications. But the method used to grow nanowires has largely been limited to using gold nanoparticles as seeds, which is not ideal in terms of the ability to dope the material and its incompatibility with common processing methods.
In an article recently published in NanoLetters, Prof. Kimberly Dick Thelander of Lund University, Sweden, and her research group demonstrated that using tin nanoparticles could not only grow semiconductor nanowires effectively, but that such nanowires exhibit interesting semiconducting properties, particularly, being an Esaki (or tunnel) diode with fast operation and a wide range of operating frequencies. This work was featured as a research highlight by Nature Materials for its demonstration of the potential importance of using metallic seed particles metal to influence the properties of nanowires.
Prof. Thelander's research focuses on understanding the fundamental sciences of nanowire growth, and using nanowires as building blocks for complex 3D architectures. More information on her research can be found on her website here.
