Abstract
Colloidal nanocrystals (quantum dots (QDs)) of mercury selenide have been synthesized and the effect of size quantization on their basic properties has been investigated. The current-voltage characteristics of single QDs (less than 10 nm) had features in the form of separate regular peaks and quasi-periodic current oscillations with voltage intervals (0.1-0.2) V. The observed features were explained in the models of size quantization and Bloch oscillations. The absorption spectra in the range up to 25 μm had eight certain peaks, including five --- interband and intraband transitions and three --- with energies (145-215) meV, which are explained as intraresonant. Calculations show that it is possible to have IR photosensitivity in the wavelength range up to 40 μm. Keywords: Colloidal synthesis, nanocrystal, quantum dot, mercury selenide, dimensional quantization, Bloch pulsations, electron transport, IR absorption, IR photosensitivity.
