By adapting the basic units to exactly defined natural constants, the quantized Hall resistance (QHR) standards are also given precisely. The Von Klitzing constant RK = h/e2 (h Planck's constant and e elementary charge) can be measured precisely using the quantum Hall effect (QHE) and is thus the primary representation of the ohm. Currently, the QHR standard based on GaAs/AlGaAs heterostructure has succeeded in yielding robust resistance measurements with high accuracy ", author = "{Momeni Pakdehi}, Davood", note = "Doctoral thesis", year = "2020", doi = "10.15488/10201", language = "English", school = "Leibniz University Hannover", }
