Electron mobility, , vs for and . Different symbols refer to samples from this work (full dots: ; triangles and guide for the eye: ) and from the literature (asterisk: Ref. 9; stars: Ref. 10; circles: Ref. 11). The dotted line is the calculated mobility for from Ref. 12. The inset shows the resistivity, , for at different and . Lines are guides to the eye.
(a) vs at for ( and 0.1%). The inset shows the -dependence of at different . (b) vs at different for (top) and (bottom).
vs for (, 0.1%, and 0.2% and ). The dotted lines show dependencies of on and . These lines cross at a characteristic magnetic field (see arrow) corresponding to the condition .
(a) -dependence of , (b) , and (c) for (, 0.1%, and 0.2%). Lines are guides to the eye.
