About This Quiz

The Quantum Hall Effect is otherwise known as the integer Quantum Hall Effect it is the Quantum Theory or quantum physics view of the Hall effect which is the production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor and applied to the magnetic field perpendicular to the current.

    For Quantum Hall Efffect, the Hall effect was observed in how many dimensional electron system? - ProProfs

    For Quantum Hall Efffect, the Hall effect was observed in how many dimensional electron system?

    • 1

    • 2

    • 3

    • 4

    Correct Answer
    A. 2
    Explanation
    The correct answer is 2 because the Quantum Hall Effect is observed in a two-dimensional electron system. In this phenomenon, when a magnetic field is applied perpendicular to the plane of the system, the electrons experience a Lorentz force that causes them to move to one side of the system, creating a voltage difference across the material. This effect is only observed in systems with two dimensions, such as a thin semiconductor layer or a graphene sheet. In three-dimensional systems, the electrons are free to move in all directions, and the Hall effect is not as pronounced.

    Who discovered Hall conductivity was quantized?  - ProProfs

    Who discovered Hall conductivity was quantized? 

    • Michael Pepper

    • Gerhard Dorda

    • Klaus Von Klitzing

    • Robert Laughlin

    Correct Answer
    A. Klaus Von Klitzing
    Explanation
    Klaus Von Klitzing discovered that Hall conductivity was quantized. This discovery, known as the Quantum Hall Effect, earned him the Nobel Prize in Physics in 1985. Von Klitzing's work showed that at low temperatures and strong magnetic fields, the Hall conductivity of a two-dimensional electron gas becomes quantized, meaning it can only take on discrete values. This groundbreaking finding opened up new avenues for studying the behavior of electrons in condensed matter physics and has important implications for the field of quantum mechanics.

    Who discovered the Hall effect? - ProProfs

    Who discovered the Hall effect?

    • James Phills Hall

    • Edwin Hall

    • Hall Mark

    • Edwards Hall

    Correct Answer
    A. Edwin Hall
    Explanation
    Edwin Hall is the correct answer for the question "Who discovered the Hall effect?" The Hall effect is a phenomenon in physics that was discovered by Edwin Hall in 1879. He observed that when a magnetic field is applied perpendicular to the flow of an electric current in a conductor, a voltage difference is created across the conductor. This voltage difference is known as the Hall voltage and is proportional to the strength of the magnetic field and the current flowing through the conductor. Edwin Hall's discovery of this effect has been significant in understanding the behavior of electrons in materials and has led to various applications in fields like electronics and solid-state physics.

    Which of these semi conductors is widely used in IQH experiments? - ProProfs

    Which of these semi conductors is widely used in IQH experiments?

    • Silicon

    • Diamond

    • Boron arsenide

    • Gallium arsenide

    Correct Answer
    A. Gallium arsenide
    Explanation
    Gallium arsenide is widely used in IQH (integer quantum Hall) experiments. It is a compound semiconductor that exhibits high electron mobility and a large energy gap, making it suitable for studying quantum phenomena. Its unique properties allow researchers to observe the quantum Hall effect, which occurs when a two-dimensional electron gas is subjected to a strong magnetic field and exhibits quantized resistance values. Gallium arsenide's popularity in IQH experiments is due to its excellent electronic properties and its ability to provide a controlled environment for studying quantum effects.

    What will determine if the Quantum Hall is IQHE or FQHE? - ProProfs

    What will determine if the Quantum Hall is IQHE or FQHE?

    • Elementary charge

    • Planck's constant

    • Pre-factor value

    • Hall Voltage

    Correct Answer
    A. Pre-factor value
    Explanation
    The pre-factor value is what determines whether the Quantum Hall effect is IQHE (Integer Quantum Hall Effect) or FQHE (Fractional Quantum Hall Effect). In the IQHE, the pre-factor value is an integer, while in the FQHE, the pre-factor value is a fraction. This distinction is crucial in understanding the behavior of electrons in the Quantum Hall effect and the formation of quantized energy levels.

    What does FQHE majorly depends on? - ProProfs

    What does FQHE majorly depends on?

    • Electron - electron interaction

    • Fractional observation

    • Planck's constant

    • Hall Plateau

    Correct Answer
    A. Electron - electron interaction
    Explanation
    FQHE, or Fractional Quantum Hall Effect, majorly depends on electron-electron interaction. This phenomenon occurs in a two-dimensional electron gas subjected to a strong magnetic field and low temperatures. The interaction between electrons plays a crucial role in FQHE, leading to the formation of fractional charge and fractional statistics. This effect is observed as a series of plateaus in the Hall resistance, known as the Hall Plateau, which is a characteristic feature of FQHE. Planck's constant is a fundamental constant in quantum mechanics but is not directly related to FQHE.
