Photonic hall effect

Classic hall effect measurement system is to read voltage difference made between both diagonal sides, when flowing current and applying magnet field strength, in perpendicular to flowing current direction.

Photonic hall effect measurement is to read various electrical properties by illuminating light of “various range of wavelength” on the sample, in addition to flowing current and applying magnet field strength.

It is great to see “RGB (Red, Green, Blue), Light intensity vs carrier density, carrier mobility, resistivity, hall coefficient

│Why photonic hall effect measurement system is required ?│

Light source system has been required , which is able to illuminate light of solar and various wave length of light(i.e. R,G,B) on the sample in uniformity.
- In regards to solar cell and optical sensor, it should be better experiment to measure hall effect (electrical parameters, kind of carrier density, carrier mobility, resistivity , hall efficient and etc), on condition of illuminating various wavelength of light, at the same time.

• Ecopia developed light source system, using Xe Lamp, Hallogen Lamp for applying light on the sample in uniformity. Simulator
• In addition to light source system, we developed “Optical focusing prism” that makes light illuminate on sample in uniformity
• This light source system and optical focusing makes it possible to measure hall effect, as well as “solar simulator” function.

│How “photonic hall effect measurement system” should consists of ?│

↑Main body ( Constant current source )

Below picture is to show magnet kit with “illuminating light” module by light source.
( Actual providing system may be a little different from below image, since we are updating our instrument for better improvement ).

If you already have “AMP55T” magnet kit + HMS-5000 main body, you can update it into photonic hall effect measurement system by modifying “magnet kit”, attaching “light focusing prism” and light source system (Red, Green, Blue) also.
