Open orbits. an open orbit in a monovalent tetragonal metal connects opposite faces of the boundary of a brillouin zonc. the faces are separated by g 2x 10 cma magnetic field b 10* gauss 10 tesla is normal to the plane of the open orbit. (a) what is the order of magnitude of the period of the motion in k space? take t 10 cm/sec. (b) describe in real space the motion of an clectron on this orbit in the presence of the magnctic field chapter 9 problem 5p share collapse all a step 1 given that g 2 x 10 cm c 3 x 10 cm s e 5 x 10 esu v10 cm d b-10 gauss age period of the motion, t= evb by substituting the corresponding values, e)(2x10° cm")(3x10® cm: ") (1049 erg sec t= (5x10 esu)(10 cm d')10° gauss) t = 12x100 step 2 b) the electron moves in a direction normal to the fermi surface in a straight line if the fermi surface is closer to planar in the region of interest but, magnetic field makes move slowly in small up and down or side, somewhat unusual manner, but we expect in helical manner was this solution ?

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?
