Solution growth of n-type - single crystals using Sn solvent

Solution growth of n-type β-FeSi2 single crystals using Ni-doped Zn solvent

“…The mobilities of n-type crystals were 3-6 cm 2 /V s, which are approximately one order of magnitude lower than the value of p-type crystal. The values of our mobility were similar to typical values of n-type b-FeSi 2 single crystals grown by CVT and TGSG method [4,5,7]. Fig.…”

“…The p(T) and n(T) curves of ]1 and ]2 had two different slopes in the carrier freeze-out region due to the difference of compensation conditions. We analyzed the p(T) and n(T) curves by means of a simple carrier compensation model [5,7]. The results are given in Table 2, where E D and E A are the ionization energy of donor and acceptor, and N D and N A the densities of donor and acceptor, respectively.…”

“…Kannou et al [4] and Udono et al [5] reported that these single crystals are grown using Sb and Sn solvents ; however, their resistivity is approximately 10 times higher than that of Ga solvent. In addition, the size of the n-type crystal is insufficient to allow measurement of the precise thermoelectric properties.…”

Optical and electrical properties of β-FeSi2 single crystals

“…These E d values are extremely close. The results are consistent with those of n-type b-FeSi 2 single crystals prepared by the temperature-gradient solution growth method [18]. Therefore, it can be concluded that the kinds of the impurities in every samples are the same.…”

Thermoelectric Properties of Solution Grown &beta;-FeSi<SUB>2</SUB> Single Crystals

“…[7][8][9][10][11] In this paper, we report the low-temperature thermoelectric properties of p-type -FeSi 2 single crystals grown by a temperature gradient solution growth (TGSG) method using Ga solvent.…”
