    • An attempt to measure the valley gap using an optical technique was made by I.V. Kukushkin, JETP Lett. 45, 276 (1987). Later, it was shown by V.M. Apalkov and E.I. Rashba, ibid. 53, 442 (1991); and verified experimentally by I.V. Kukushkin et al. Europhys. Lett. 22, 287 (1993), that the previously used way of data treatment is inappropriate for extracting the gap value from optical data.

    • An attempt to extract the valley gap from the chemical potential jump measured at v = 3, 5, and 7 was made by V.M. Pudalov et al. [JETP Lett. 41, 325 (1985); Sov. Phys. JETP 62, 1079 (1985)] based on a sophisticated model which yielded considerably larger values of the gap as compared to the raw data. Because of the poor accuracy, their results could be equally well described by both linear and square-root magnetic field dependences of the gap and, therefore, they were not in contradiction to the conventional theory of exchange-enhanced gaps of Ref. 11.
