“…Detailed experimental consideration of the thermoelectricity in doped PbSe has thus far been lacking, with few recent studies 9,10 in this area. The most significant work was performed by Alekseeva et al, 9 and the doping levels in this study were not well quantified.…”

High-temperature thermoelectric performance of heavily doped PbSe

We present a model calculation, employing first-principles calculations as well as empirical data, which suggests that properly hole-doped bulk PbSe may show a Seebeck coefficient as high as 230 V / K, in a temperature regime in which the lattice thermal conductivity is rather small. It may therefore show a figureof-merit ZT as high as 2 for temperatures of 1000 K. Heavily doped p-type PbSe may offer better thermoelectric performance than the sister material, optimized PbTe, for high-temperature applications such as power generation.

“…It is attractive in various applications such as laser materials [4], solar cells [5], infrared detectors [6], near-IR luminescence [7] and thermoelectric devices [8]. In the past few years, various methods including sonochemical synthesis [9], hydrothermal/solvothermal synthesis [10,11] and chemical bath deposition method [12] have been used to prepare PbSe nanocrystals since they are able to the control over size and morphology.…”

Monodispersed PbSe nanocubes were synthesized through a simple hydrothermal method by using Pb 2+ -EDTA complex and Na 2 SeSO 3 . Composition and morphology of the samples were characterized by means of XRD, TEM and SEM. The gradually releasing of Pb 2+ from Pb 2+ -EDTA complex, and the adopting of PVP can adjust the growth rate in <100> and <111> directions of PbSe. Both Pb 2+ -EDTA complex and PVP played important roles in the crystal growth of the monodispersed PbSe nanocubes. In addition, UV-vis and photoluminescence properties were characterized. E g of the PbSe nanocubes is 1.5 eV approximately, which is much larger than that of bulk PbSe. Under PL excitation at 406 nm, a red emission peak at 696 nm is observed, showing that the synthesized PbSe is luminescent nanomaterials.

“…In addition, PbSe nanocrystals have major industrial uses such as infrared detectors, light emitting devices, field effect transistors etc. Due to their unique electronic, optical, and physical properties [14]. Selenides have been widely used as thermoelectric cooling materials, optical filter, optical recording materials, solar cell materials, superionic materials, and sensor and laser materials [15].…”

In the present work, PbSe nanostructures have been synthesized by using [bis(salicylate)lead(II)]; [Pb(Hsal) 2 ]; as lead precursor in the present of sonochemical method with water solution. Besides, the effects of time and power of ultrasonic, surfactant and ultrasonic radiation on the morphology and particle size of products were studied by SEM images. It was found out that the size and morphology of the products were greatly influenced by these parameters. The size of the sample as prepared was calculated by Debye-Scherrer formula according to XRD spectrum to be about 12 nm. Similar result can also been obtained in the TEM image. The XRD studies indicated the production of pure cubic PbSe nanostructures could only happen in the presence of ultrasonic radiation.
