Elektron sisteminin elektronik özellikleri Thomas-Fermi-Poisson non-lineer perdeleme teorisi ile elde edildi. Perdelenmis potansiyelin sikistirilamaz bölgelerde ve Fermi enerjisi seviyelerindeki egimden elektron hiz dagilimini konuma bagli degisimi elde edilir. Buldugumuz sonuçlari deneylerle karsilastirdik.We report on our theoretical investigation of the effects of the confining potential profile and sample size on the electron velocity distribution in (narrow) quantum Hall systems. The electrostatic properties of the electron system are obtained by the Thomas-Fermi-Poisson non-linear screening theory. The electron velocity distribution as a function of the lateral coordinate is obtained from the slop of the screened potential at the Fermi level and within the incompressible strips. We compare our findings with the recent experiments.trinfo:eu-repo/semantics/openAccessFizik ve Fizik MühendisliğiPhysics and Physics EngineeringMaster Thesis213013
