By a News Reporter-Staff News Editor at Physics Week -- Current study results on Theoretical Physics have been published. According to news reporting originating from Moscow, Russia, by VerticalNews editors, the research stated, "The problem of the effect of electron-electron interaction on the static and dynamic properties of a double-barrier nanostructure (resonant tunneling diode (RTD)) is studied in terms of a coherent tunneling model, which includes a set of Schrodinger and Poisson equations with open boundary conditions. Explicit analytical expressions are derived for dc and ac potentials and reduced (active and reactive) currents in the quasi-classical approximation over a wide frequency range."
Our news editors obtained a quote from the research from National Research Nuclear University, "These expressions are used to analyze the frequency characteristics of RTD. It is shown that the interaction can radically change the form of these expressions, especially in the case of a hysteretic I-V characteristic. In this case, the active current and the ac potentials can increase sharply at both low and high frequencies. For this increase to occur, it is necessary to meet quantum regime conditions and to choose a proper working point in the I-V characteristic of RTD. The possibility of appearance of specific plasma oscillations, which can improve the high-frequency characteristics of RTD, is predicted."
According to the news editors, the research concluded: "It is found that the active current can be comparable with the resonant dc current of RTD."
