Temperature and magnetic field effects on the carrier density and Hall mobility of boron-doped Tl–Ba–Ca–Cu–O superconductor

Mechanism of inhibition of purified leaping mullet (liza saliens) NADPH‐cytochrome P450 reductase by toxic metals: Aluminum and thallium

“…Thallium compounds have also been used as rat poison and insecticides [2]. There is an increasing demand for thallium in the high technology and future technology fields because of the role in high-temperature superconductors [2,[10][11][12]. Although thallium pollution does not present major threat at this time, the increased industrial usage might cause unrecoverable effects in the aquatic life in the near future.…”

Acoustic phonons scattering mobility and carrier effective mass in In6S7 crystals

“…The electrical resistivity (ρ) and Hall coefficient (R h ) of In 6 S 7 crystals are measured in the temperature region of 170-320 K. The experimental Hall data recording and calculation procedure was previously described [7]. The sign of the Hall coefficient indicates that the crystals exhibit n-type conductivity for all recorded data.…”

Influence of KMnO4 Substitution on the Structural and Transport Properties of Tl2Ba2Ca(Cu1-xRx)2Oδ+6 System

“…The crystal symmetry of the sample is tetragonal and the unit cell parameters of the sample (i.e., a and c) were found to be a = 3.8355°A and c = 29.6081A°, close to the typical values of the Tl-2212 phase. 16 The lattice parameters "a" and "c" as functions of KMnO 4 content are listed in Table 1. Examination of the data in the table clearly shows that the changes in the lattice parameters "a" and "c" are insignificant.…”

“…14,15 Variation of the carrier concentration (particularly holes) in the CuO 2 planes, unbinding of the Cooper pairs and carrier localisation induced by the structural disorder are also useful for explaining the decrease in T c . 16 In this study, we have prepared superconducting samples of Tl 2 Ba 2 Ca(Cu 1-x R x ) 2 O δ+6 , where R = KMnO 4 , and x = 0.5, 1.0 and 2.0 using a solid-state reaction technique. Microstructure, electrical, and magnetic properties of these samples were investigated.…”
