Abstract
The thermodynamic characteristics of weakly interacting electron gas in CdSe nanoplatelet are theoretically studied. In the Boltzmann approximation, the partition function of the system is precisely calculated, and it is shown that it is expressed through the Ramanujan theta function. The dependences of the entropy and heat capacity on the size of the nanoplatelet are determined. The temperature behavior of the heat capacity of the gas of electrons in low- and high-temperature regions is analyzed.
期刊介绍:
Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section.
Theoretical as well as experimental papers are accepted.
