Spectral Method for Solving the Differential Equations Involved in Ab-initio Treatment of Tunnel Transistors Structures

چکیده
In lucrare este prezentată o nouă variantă a metodei spectrale de rezolvare a ecuaţiilor diferenţiale cu condiţii la limită, aplicabilă la calcule ab-initio pentru tunelarea electronilor. Prin exprimarea potenţialului total în care se mişcă electronul ca o dezvoltare în serie după un anumit set de funcţii într-un spaţiu Hilbert, ecuatiile obtinute prin metoda colocatiei pot admite o integrare analitica initiala. Experimentele noastre numerice au aratat o îmbuntăţire importantă a preciziei datorită acestei prelucrări analitice suplimentare, ceea ce, împreună cu propritatea de evanescentă poate conferi metodei avantaje importante pentru calcule ab-initio.
