The term ordinary Hall effect can be used to distinguish the effect described in the introduction from a related effect which occurs across a void or hole in a semiconductor or metal plate when current is injected via contacts that lie on the boundary or edge of the void. The charge then flows outside the void, within the metal or semiconductor ...
Although Sega pioneered the use of Hall effect sensors in their Sega Saturn 3D controller [32] and Dreamcast stock controller [33] from the 1990s, Hall effect sensors have only started gaining popularity for use in consumer game controllers since the early 2020s, most notably in analog stick/joystick and trigger mechanisms, [34] for enhanced ...
A Hall-effect magnetic field sensor is then used to measure the induced current with its output being directly proportional to the magnitude of the current flowing. In the simplest configuration, a Hall-effect magnetic field sensor can be placed adjacent to the conductor and its output measured but there are limitations.
Differential Hall Effect Metrology (DHEM) is an electrical depth profiling technique that measures all critical electrical parameters (resistivity, mobility and carriers) through an electrically active material at sub-nanometer depth resolution. [1] [2] DHEM is based on the previously developed Differential Hall Effect (DHE) method. [3]
The planar Hall sensor is a type of magnetic sensor based on the planar Hall effect of ferromagnetic materials. [1] [2] It measures the change in anisotropic magnetoresistance caused by an external magnetic field in the Hall geometry. As opposed to an ordinary Hall sensor, which measures field components perpendicular to the sensor plane, the ...
The Hall effect type is more sensitive and is able to measure both DC and AC, [1] in some examples up to the kilohertz (thousands of hertz) range. This type was often used with oscilloscopes , and with high-end computerized digital multimeters, however, they are becoming common place for more general use.

The fractional quantum Hall effect is more complicated and still considered an open research problem. [2] Its existence relies fundamentally on electron–electron interactions. In 1988, it was proposed that there was a quantum Hall effect without Landau levels. [3] This quantum Hall effect is referred to as the quantum anomalous Hall (QAH) effect.
