In this paper we focus on the implementation of a process flow of SB-MOSFETs into the process simulator of the Synopsys TCAD Sentaurus tool-chain. An improved structure containing topography is briefly discussed and further device simulations are applied with the latest physical models available. Key parameters are discussed and finally the results are compared with fabricated SB-MOSFETs in terms of accuracy and capability of process simulations.

Energy converters using the phenomenon of thermionic emission to generate electricity and their applications related to renewable energy sources (RES) have been presented. Taking into account new technical solutions, hybrid systems combining thermionic energy converters (TEC) with other energy generators, e.g. with PV cells, the Stirling engine, improving the efficiency of the entire electric energy generating system, have been described. Leading technologies related to thermionic energy conversion and TEC hybrid systems powered by solar radiation have been shown in the tables. The dynamic development of TEC technology in recent years, in our opinion, will contribute to the wider interest of research communities to use the thermionic emission phenomenon to generate electricity.

In this paper we present a simulation framework to account for the Schottky barrier lowering models in SBMOSFETs within the Synopsys TCAD Sentaurus tool-chain. The improved Schottky barrier lowering model for field emission is considered. A strategy to extract the different current components and thus accurately predict the on- and off-current regions are adressed. Detailed investigations of these components are presented along with an improved Schottky barrier lowering model for field emission. Finally, a comparison for the transfer characteristics is shown for simulation and experimental data.

W pracy przedstawiono sposób generacji energii elektrycznej w oparciu o fotonowo wzmocnioną termoemisję elektronową (ang. photon-enhanced thermionic emission - PETE), w której do przetwarzania energii promieniowania słonecznego w elektryczną wykorzystuje się zjawiska fotowoltaiczne i termoemisji elektronowj. Zaletą rozwiązania jest relatywnie wysoka sprawność energetyczna względem klasycznych metod wytwarzania energii elektrycznej, w tym, konwersji fotowoltaicznej (PV). W pracy przedstawiono podstawy działania PETE, obecny stan badań oraz dokonano analizy porównawczej konwersji PV i PETE.

The article presents new method generation of electricity by the use conversion of solar radiation. This method is the Photon-enhanced Thermionic emission - PETE, which converts solar energy into heat energy and then into electricity. The advantage of this solution is to avoid losses in relation to photovoltaic conversion (PV), resulting from the excessive heating energy converter. Presents the basics of PETE and the current state of research on this phenomenon in the world. In addition, a comparative analysis of PV conversion and PETE.

This paper traces early inquires on the nature of the work function (WF). Much attention was paid to the papers published by Einstein (1905), Richardson (1901), Jentzsch (1908), Debye (1910), Schottky (1914) and Langmuir (1916). Those authors assumed that the image force, introduced already by Thomson for macroscopic bodies, may be the main reason for the barrier at the metal surface. The formula derived by Schottky (1914) is still used for calculation of the lowering of the surface barrier in presence of an external electric field. In further development of surface physics, however, much emphasis was paid to the role of a dipole layer. However, at the end of 20th century the idea of the image potential as the main contribution to WF was restored by Brodie (1995) and subsequently improved by Halas and Durakiewicz (1998). In these theories a distance d from which the image force can be integrated is found from the uncertainty principle and from the length of spontaneous metallic plasma polarization, respectively. The last approach has appeared to be very useful in calculation of WF of conducting compounds and ionization potentials of metallic clusters.
