“…1. The ambient pressure magnitude of the activation gap is 40 K, similar to that found in a variety of previous transport and spectroscopic studies of SmB6 [4][5][6][7] but much smaller than that reported in a recent infrared transmission experiment [8].…”

“…The scattering rate has almost completely saturated for temperatures below 10 K. This temperature is considerably lower than the temperature at which the bulk hybridization gap is first observed [2]. Therefore, we argue that the formation of the Fermi-liquid that is responsible for the surface conduction should only occur at very low temperatures and may be responsible for the plateau in the resistivity at 4 K [7,8].…”

“…1, наблюдались и ранее во многих углеродных и неуглеродных объек-тах. Например, в пиролитических графитах [8], Yb при фазовом переходе полуметалл−полупроводник (под дав-лением) [13], SmB 6 [14], ультратонких сверхпроводящих гранулированных пленках Pb на SiO 2 при их толщинах свыше 35 ¦ [15], тонких (60−80 nm) пленках аморфного углерода на подложках из n-Si [3], высокопористом биоуглероде карбонизированного дерева бука [16] и т. д. Поскольку объекты самые разные, различны и механиз-мы переноса заряда, обеспечивающие характерный вид зависимостей ρ(T ). Так, в Yb эти механизмы обуслов-лены зонной структурой (незаполненными d-состояния-ми), а в SmB 6 , например, они связаны с металлической проводимостью в примесной полосе, образованной ва-кансиями Sm.…”
