Abstract:PbTe mesa diodes were fabricated from a series of p − n junctions grown on BaF 2 substrates. For this series, the hole concentration was kept constant at 10 17 cm −3 and the electron concentration varied between 10 17 and 10 19 cm −3 . Capacitance versus voltage analysis revealed that for n > 10 18 cm −3 , a one-sided abrupt junction is formed. The direct and reverse branches of the current versus voltage curves exhibited different forms among the diodes. The R 0 A product varied between 0.23 and 31.8 Ωcm 2 , … Show more
“…Under the subsequent treatment of the samples in boiling 50% NaOH solution and dilute HCl, only Те was detected on the surface. For chemical etching of the PbTe surface, a solution of Br 2 :HBr:H 2 O (volume ratio 1:40:40) can be also used [11].…”

“…At the same time due to the wide transparency in the infra-red (IR) region their optoelectronic features are very useful for applications. 2 The lattice anharmonicity results in anharmonic phonons which possess asymmetry described by third rank polar tensors, similarly to effects of second harmonic generation, linear electro-optics, piezo-electricity etc. Additionally they possess promising thermal conductivity, photostimulated thermal expansion and temperature dependent elastic constants.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
