Magnetic Field Dependence of Ballistic Heat-Pulse Scattering in As-Doped Ge

抄録

Heat-pulse propagation along the [100] axis of As (1.5×10¹⁴/cm³ and 0.9×10¹⁵/cm³)-doped Ge has been studied as a function of the magnetic field H⁄⁄[100] and of the heat-pulse temperatures ranging from 6.6 K to 9.3 K. It is shown that the transmitting heat-pulse intensity detected by CdS bolometer increases with increasing magnetic field up to 60 kG at sample temperatures ranging from 1.8 K to 4.2 K. The magnetic field dependence of the detected heat-pulse amplitude is compared with a calculation based on the Suzuki-Mikoshiba theory.
