  Title Observation of free carrier resonances in p-type germanium at submillimeter wavelengths Type Journal Article
  Year 1978 Publication Sov. Phys. Solid State Abbreviated Journal Sov. Phys. Solid State  
  Volume 20 Issue 4 Pages 573-579  
  Keywords p-Ge, free carriers, resonances  
  Abstract The spectrum of hole resonances in pure p-Ge for submillimetre in quantizing magnetic fields has been studied and identified. Measurements of photoconductivity spectra of p-Ge were made in the wave range lambda = 2-0.3 mm at temp. of 4.2-15 deg K in magnetic fields H up to 40 Measurements at various frequencies showed that the position of a series of characteristic resonances depends on the frequency of the illumination. This is in line with theoretical conclusions about the effective mass of the carriers increasing with rise in the magnetic field as a result of the interaction of the edge of the valency band with the split spin-orbital interaction of the sub 7 exp + band and the conduction band. The relative intensity of the quantum resonance lines of the free holes depends on the excitation conditions.

  Title Energy spectrum of acceptors in germanium and its response to a magnetic field Type Journal Article
  Year 1977 Publication Sov. Phys. JETP Abbreviated Journal Sov. Phys. JETP  
  Volume 45 Issue 4 Pages 769-776  
  Keywords p-Ge, photoconductivity, energy spectrum, magnetic field  
  Abstract We investigated the spectrum of the submillimeter photoconductivity of p-Ge at helium temperatures and the effects of a magnetic field up to 40 kOe on the spectrum. A large number of lines of transitions between the excited states of the acceptors was observed, some of the lines were identified, and the energies of a number of spectral levels B, Al, Ga, In, and TI in Ge were identified. The results are compared with calculations and with experimental data obtained from the spectra of the photoexcitation of the ground state of the impurities. Using one transition as an example, we discuss the splitting of the excited states of acceptors in the magnetic field and under uniaxial compression.
