Shubnikov-de Haas oscillations in Cd3P2

Semiconducting Compounds of the AII BV Group

“…The cyclotron effective mass m� = 0.061 mo has been determined fo r Cd3P 2 from an analysis of Shubnikov de Haas (SdH) oscillations fo r a sample with electron concentration n = 1.2 x 10 2 4 m -3 (59). The results are not consistent with a simple ellipsoidal energy model and additional measurements are necessary.…”

The Shubnikov–de Haas Effect in Semiconductors: A Comprehensive Review of Experimental Aspects

“…Heller et al (1971) first observed SdH oscillations and determined m* from the temperature dependence of the amplitude. It is an η-type degenerate semiconductor with electron concentrations lying in the range from 1 χ 10 17 to 5 χ 10 18 cm" 3 for undoped samples.…”

The g-factor of conduction electrons in Cd3P2 at low temperatures

“…However, broadening of energy levels due to collisions depends on the quality of the samples. We have made an estimate of this level broadening from the results of Heller et al 16 on the 1.23 • 1018 cm -3 Cd3P2 sample. The value of TD was found to be approximately 17 K,* which is equivalent to a broadening of about 1.5 meV.…”

“…Heller et al16), kF is related to the electl;on concentration framework of the electronic energy-band structure model proposed by Jay-Gerin et al17 for CdaP2 at low temperatures, the dependences of m*(EF) and Ev upon n (expressed in cm -3) are given by m*(EF)/mo ~Eo[(1 +0.497 x 10-12~12/3) 1/2-1]+0.00365 x 10-12n 2/3 (in eV)(5) respectively. Let us note that the last term on the right-hand side of Eq.…”
