Products Description

CVD Diamond Wafer

Diamond is a wide bandgap semiconductor material with excellent performance and has many advantages: Extremely high thermal conductivity: thermal conductivity 2200W/mK, diamond has the highest thermal conductivity at room temperature ; extremely high dielectric breakdown characteristics: breakdown electric field is 107V/cm, 50 times that of GaAs, 2 times that of GaN, SiC 2.5 times ; extremely high power capacity: the allowable power capacity is more than 2500 times that of Si material; especially suitable for making high-power electronic devices; low dielectric constant: the dielectric constant is 5.7, about 1/2 of GaAs , which is less than half of InP ; high saturation carrier velocity: the saturation carrier velocity is 12.7 times that of GaAs, Si or InP, and maintains a high rate when the electric field strength increases ; high carrier mobility: electron mobility It is 4500c/(V s), which is higher than most materials, and is suitable for making high-frequency electronic devices . Main feature: Wide light transmission range (220nm~50um) Higher thermal absorption coefficient than other optical materials Ultra low absorption Chemical damage and scratch resistance Shape and size can be customized low birefringence
