Abstract
Mūsdienu nanoelektroniskas ierīces ļauj precīzi manipulēt atsevišķu elektronu stāvokļus,
izmantojot elektrostatiski vadāmās tuneļbarjeras. Elektronam piemīt lādiņš un
enerģija, tāpēc ir iespējams precīzi kontrolēt arī tunelēšanas strāvas un siltuma plūsmas.
Darbā tiks pētīta enerģijas pārnese elektronu kvantu sūkņos, izmantojot elektrostatiski
vadāmo tuneļbarjeru fenomenoloģiskus modeļus un kinētiskos vienādojumus. Sūkņa darbība
notiks līdzsvara režīmā, ļaujot saistīt modeļa mikrostāvokļus ar ierīces temperatūru.
Nowadays nanoelectronical devices give us an opportunity to precisely control singleelectron state using electrostatically controlled tunneling barriers. Electron has a charge and an energy so it is possible also to precisely control tunneling electric current and heat fluxes. In this work we research the transport of an energy in quantum pumps using master equations and fenomenological models of tunneling barriers. The pump will be modeled working in the equilibrium regime, thus enabling to connect microstates of the model with the temperature of a device.
