Assume that the E versus K relationship for electrons in the conduction band of a hypothetical tetravalent n-type semiconductor can be approximated byE = ak + c. Consider c is constant. The cyclotron resonance for electrons in field B = 0.15 Wb/m- occurs at an angular radiation frequency we = 2 x 101 rad/sec. Find the value of a. Consider the mass of the electron as the effective mass when it accelerated by the cyclotron. (a) 4.6 x 10-38 J - m2 (b) 5.9 x 10-38 J - m2 (c) 7.7 x 10-38 J - m2 (d) 9.8 x 10-38 J - m
