Product Introduction

In addition to synthetic diamond, high impedance intrinsic silicon (high impedance silicon) materials are suitable for a wide range of applications(1.2 µm)reachMm (1000 µ m or even 8000 µ m)µm)Wave'sSame sexCrystal materialsCompared to diamonds, it is much cheaper and easier to grow and manufacture. And he is larger in size and easier to manufacture,THzThe rapid development of technology is based on this advantage. aboutTHzApplication, we provide in1000 µm (For longer wavelengths,3000even to the extent that8000micron)Transmittance reaches50-54%ofHigh Resistivity Float Zone Silicon (HRFZ-Si)High impedance floating region intrinsic silicon materials and related optical components.

The dielectric constant of synthetic electrolyte silicon is determined by its conductivity (e.g. free electrons)-Carrier concentration). chart3What is displayed is in1THzBelow, the dielectric constant of silicon at different purities.The low doping dielectric constant is close to the true value, approximately equal to the high-frequency dielectric constant. As the doping concentration increases, the true dielectric constant will become negative and cannot be ignored. The dielectric constant characterizesTHzThe transmission loss characteristics of waves. The loss coefficient can be calculated using the following formula:tanδ=1/(ω*εv*ε0*R),hereω –Circular frequency, εv –Dielectric constant under vacuum（8.85*10-12 F/m）.ε0 –The dielectric constant of silicon(11.67), RIt is the resistance value. For example,1THzBelow,10 kOhmResistance valueHRFZ-SiThe loss coefficient is1.54*10-5.
