- Abstract
The results of studying the concentration and temperature dependences of NQR spectrum parameters inherent to I127 in mixed layered semiconductors Pbx-1CdxI2 and (BiI3)(1-x)(PbI2)x are presented for x ≤ 0.30 and T = 77 ... 150 K. It has been shown that, for the low content x ≤ 0.08 PbI2 for (BiI3)(1-x)(PbI2)x and x ≤ 0.02 CdI2 for Pb1- -CdxI2, the temperature coefficients of NQR frequency don't undergo significant changes, which is indicative of conservation of the quasi-two-dimensional nature of the vibration states. The possibility to form nanoclusters of PbI2 and CdI2 as well as their influence on the parameters of the NQR spectra has been discussed.
