Title: Electrical parameters of polycrystalline Sm{sub 1–x}Eu{sub x}S rare-earth semiconductors

Abstract

The electrical parameters of polycrystalline Sm{sub 1–x}Eu{sub x}S compounds are studied. The conductivity, concentration of free electrons, their mobility, and the conductivity activation energy are measured as functions of the quantity x. The structural parameters of the compounds are determined. A heterostructure is fabricated with x in the range from 0 to 0.3, and the electrical voltage generated by the structure, when heated to a temperature of T = 450 K, due to the thermovoltaic effect is measured. This voltage is found to be 55 mV. A method for measuring the thermally induced voltage is described. The method provides a means for separating the thermovoltaic effect from the Seebeck effect.

  • Single crystals of LiErF/sub 4/ and LiHoF/sub 4/ have been grown and their magnetic properties measured from 1.3 to 300/sup 0/K. LiHoF/sub 4/ turned out to be a nearly ideal Ising ferromagnet with T/subC/ = 1.30 plus-or-minus 0.05 K and a saturation magnetization along the crystalline c axis of (6.98 plus-or-minus 0.02) ..mu../subB/. In LiErF/sub 4/ no ordering was observed, but extrapolation indicates that below 0.5 K it will be ferromagnetic with the magnetic moments in the crytalline ab plane. From the susceptibilities the crystal-field parameters B/subm//subn/ with (n, m) = (2,0), (4.0), (4,4), (6,0), (6,4) have been extracted givingmore » for Er/sup 3 +/ in LiErF/sub 4/: 430., -985., 1185., -5., 740. + i135. (cm/sup -1/) and for Ho/sup 3 +/ in LiHoF/sub 4/: 470.,-825., 1050., -10., 760. + i150. (cm/sup -1/). The exchange constants were found to be small compared to the dipole interactions. Furthermore the /sup 7/Li NMR spectra have been obtained in these materials as well as in LiTbF/sub 4/ thereby determining the second-order crystal-field parameters at the Li site: q = 0.0363, 0.0354, and 0.0343 A/sup -3/ for the Er, Ho, and Tb compound, respectively. The crystal-field parameters are compared to values calculated from point charges, showing agreement at the Li sites but not at the rare earth sites. (AIP)« less
  • A numerical model for the calculation of the electrical characteristics of polycrystalline ceramic semiconductors is suggested. The model is applicable in a situation where the average grain size is comparable with the depletion region width near a grain boundary and the double Schottky barriers of neighboring boundaries overlap. The two-dimensional calculation is carried out in the diffusion-drift approximation using the Voronoi grid method. The effect of crystalline grain size on the current-voltage characteristic and specific capacitance of the material is analyzed using p-SrTiO{sub 3} as an example.
  • Nitrogen oxides (NO{sub x}) gases emitted into the atmosphere cause air pollution and bring about a serious deterioration of the environment. Those gases are mainly exhausted from on-site facilities such as petroleum power plants and moving vehicles such as automobiles. Rare earth cuprates which show semiconducting characteristics were prepared and their NO{sub x} sensing characteristics have been investigated. In the rare earth cuprates, p-type semiconducting cuprates of Tm or Yb formulated as Ln{sub 2}Cu{sub 2}O{sub 5} (Ln = Tm, Yb) responded to NO{sub 2}, while the n-type cuprate of Tb did not. In the p-type semiconducting cuprates, the Yb{sub 2}Cu{submore » 2}O{sub 5} cuprate was more sensitive than Tm{sub 2}Cu{sub 2}O{sub 5}. The resistivity of the Yb{sub 2}Cu{sub 2}O{sub 5} cuprate decreased monotonically with the increase of NO{sub 2} gas concentration. In contrast to NO{sub 2} sensing, the Yb{sub 2}Cu{sub 2}O{sub 5} cuprate did not respond to NO at all. The NO{sub 2} sensor comprised of the p-type Yb{sub 2}Cu{sub 2}O{sub 5} cuprate showed a continuous and accurate NO{sub 2} detection with high selectivity.« less
  • Selenides of La, Er, and Y and tellurides of La, Er, Gd, and Y were prepared by direct reaction of the elements. Measured electrical characteristics indicate semiconducting behavior, with the possibility that a wide range of properties can be obtained within these series of rare earth compounds. Observed room-temperature resistivities, for example, ranged from about 10/sup -4/ ohm-cm for La/sub 2/Te/sub 3/ and ErSe to the insulator range for Y/sub 2/Se/sub 3/. All the compounds prepared possess high melting points (1400 deg -2000 deg C) and exhibit good thermal stability. The dissociation pressure of Gd/sub 2/Te/sub 3/ at its meltingmore » point appears to be as low as 0.01 atm. (auth)« less
