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.
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.
– solar panels,
– night vision devices,
