Growth of PBI2 single crystals from stoichiometric and Pb excess melts

Electrical characteristics of lead iodide crystal devices on flexible substrate under mechanical tensile strain

“…a and b, respectively. XRD measurement (Bruker D8) results show that the slices are single crystals with 2H structure and agree well with values in the PDF cards (No. 07‐0235) from the Joint Committee on Powder Diffraction Standards (JCPDS), shown in Fig.…”

Influence of doping and non-stoichiometry on the quality of lead iodide for use in X-ray detection

“…Taking into account the high density of impurity inclusions of sample 35 these differences in the rocking curves can be explained. On the other hand, the smallest FWHM measured was 132 arcsec and is comparable to the value of 120 arcsec determined by Hayashi et al [5]. From the 0004 rocking curves the lattice constant c was determined by the Bond method [12] as a function of sample position (Fig.…”

“…8-10. Low temperature PL spectra of the measured samples are characterized by two bands [4,5,10,14,15]. The high energy band at 496 nm (labeled BE) is due to excitonic recombination and the broader band (labeled D-A) at 510 nm is assigned to shallow donor related transitions, such as donor-acceptor pair recombinations.…”

“…Following the analysis of polycrystals prepared by direct synthesis we can suggest that crystal growth with an excess of lead is suitable for producing single crystals with the c-axis parallel to the growth direction [5].…”

“…Preparation of high quality and low defect lead iodide (PbI 2 ) single crystals for use in roomtemperature nuclear radiation detectors has been reported [1][2][3][4][5][6][7][8]. PbI 2 is a promising wide band gap material (2.32 and 2.55 eV at 4 K) with high atomic numbers of its constituents (Z Pb =82, Z I =53), low vapor pressure, high chemical stability and does not undergo structural transitions up to its melting point, T m ( $ 410 1C).…”
