I¹²⁷ NQR spectra of Pb₁₋ₓCdₓI₂ and (BiI₃)₍₁₋ₓ₎(PbI₂)ₓ of mixed layered semiconductors
The results of studying the concentration and temperature dependences of NQR spectrum parameters inherent to I¹²⁷ in mixed layered semiconductors Pb₁₋ₓCdₓI₂ 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 Pb₂ for (BiI₃)₍₁₋ₓ₎(Pb...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The results of studying the concentration and temperature dependences of NQR spectrum parameters inherent to I¹²⁷ in mixed layered semiconductors Pb₁₋ₓCdₓI₂ 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 Pb₂ for (BiI₃)₍₁₋ₓ₎(PbI₂)ₓ and x ≤ 0.02 CdI₂ for Pb₁₋ₓCdₓI₂, 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 of forming nanoclusters of Pb₂ and CdI₂, and their influence on NQR spectral parameters, has been discussed.
