Studies on thin films of lead chalcogenides

Synthesis and characterization of semimagnetic semiconductor Pb1−xSmxSe

“…The activation energy values E σ of the materials were calculated by assuming thermal-activation-type conduction and were presented in Table 1. The results of other workers [29][30][31] on lead salts support the thermally activated conduction. On the other hand, the observed behaviour of the electrical conductivity of DMS with T was explained as follows.…”

Structural and dc conduction studies on PbTe thin films

“…The estimated lattice cell parameters for as-deposited and annealed films are given in Table 2. The computed lattice constant 'a' is in good agreement with the JCPDS (78-1905) value and with earlier investigations [7,8,10,11]. There is an increase in crystallite size and decrease in strain as well as dislocation density as annealing temperature increases.…”

“…The observed d-spacing and hkl planes are given in Table 1, which are in good agreement with the JCPDS (78-1905) data corresponding to cubic PbTe, and earlier reports [7][8][9][10][11][12][13] conform the rock salt (NaCl) structure of the PbTe film. In the XRD pattern, a prominent diffraction peak at 27.52°, which corresponds to the (200) plane, indicates that the crystallites predominantly grow in this direction [7,[10][11][12]. Figure 1b and c depicts the X-ray diffractogram of annealed films in which the peaks are observed with greater intensity than the peaks observed in Fig.…”

Electrochemical Studies of Lead Telluride Behavior in Acidic Nitrate Solutions

“…Various methods are used for PbTe films preparation, but among them vacuum deposition techniques (e.g. thermal evaporation [2], molecular beam epitaxy [3]) has been used most often. Electrochemical deposition of PbTe has been developed since late 1990s [4,5].…”
