Phys. Rev. Lett. 86, 3120–3123 (2001)Order-Disorder Transition in Nanoscopic Semiconductor Quantum RingsReceived 31 August 2000; published in the issue dated 2 April 2001 Using the path integral Monte Carlo technique we show that semiconductor quantum rings with up to six electrons exhibit a temperature, ring diameter, and particle number dependent transition between spin ordered and disordered Wigner crystals. Because of the small number of particles the transition extends over a broad temperature range and is clearly identifiable from the electron pair correlation functions. © 2001 The American Physical Society URL:
