Black silicon absorbs all falling on it light

Black silicon.

 

 

The surface of the black silicon covered with a multitude of microscopic conical protrusions (cones), which give it special properties – it absorbs all falling on it light.

Description:

Black silicon – a new material obtained artificially by irradiation of silicon by short-pulse the particular powerful laser in the atmosphere of sulphur hexafluoride.

Color – black. The surface of the black silicon covered with a multitude of microscopic conical protrusions (cones), which gives it special properties. Semiconductor.

 


Properties and benefits:

– the unique feature to absorb all impinging on the light, that is the albedo of the black silicon tends to zero,

extremely high sensitivity: – 100 – 500 times higher than conventional silicon detector

– able to absorb two times more visible light than conventional silicon,

the ability to perceive and absorb infrared radiation in contrast to conventional silicon detectors.

 

Application:

solar panels,

image sensors,

– night vision devices,

– microelectronics,

etc.
