Quantum Hall Effect as a Resistance Standard
In a two-dimensional electron gas system, the Hall resistance at low temperatures and in strong magnetic field has plateaus as a function of the number of electrons that can be linked to natural constants as RH = h/ie. Due to the high precision of the measurement, the quantization of the Hall resistance is now used as the primary standard of resistance. The paper describes the use of quantum Ha...
متن کاملGeneration of Seed Perturbations from Quantum Cosmology
The origin of seed perturbations in the Universe is studied within the framework of a specific minisuperspace model. It is shown that the ‘creation’ of the Universe as a result of a quantum transition from a flat empty spacetime would lead to a flat FLRW (Friedmann Lemâıtre RobertsonWalker) Universe with weak inhomogeneous perturbations at large wavelengths. The power spectrum of these perturba...
متن کاملThe quantum Hall effect
most physical phenomena that occur in nature. Its basic equation, the Schrödinger equation, accurately describes the electronic properties of solids—of great importance in modern technology.To describe the behavior of particles that travel near the speed of light, such as neutrinos, the theory must be modified to take Einstein’s theory of relativity into account. This was accomplished by physic...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
The quantum Hall effect as an electrical resistance standard
The quantum Hall effect (QHE) provides an invariant reference for resistance linked to natural constants. It is used worldwide to maintain and compare the unit of resistance. The reproducibility reached today is almost two orders of magnitude better than the uncertainty of the determination of the ohm in the international system of units SI. In this article, mainly the aspects of the QHE releva...
