Phys. Rev. Lett. 93, 176808 (2004) [4 pages]Evidence of a First-Order Phase Transition Between Wigner-Crystal and Bubble Phases of 2D Electrons in Higher Landau LevelsSee Also: Publisher's Note Received 23 January 2004; published 22 October 2004; corrected 8 February 2005 For filling factors ν in the range between 4.16 and 4.28, we simultaneously detect two resonances in the real diagonal microwave conductivity of a two-dimensional electron system (2DES) at low temperature T≈35 mK. We attribute the resonance to Wigner-crystal and Bubble phases of the 2DES in higher Landau Levels. For ν below and above this range, only single resonances are observed. The coexistence of both phases is taken as evidence of a first-order phase transition. We estimate the transition point as ν=4.22. © 2004 The American Physical Society URL:
