Polycrystalline Diamond Wafers

Free-standing polycrystalline diamond wafer
Free-standing polycrystalline diamond wafer, 6.6 cm outside diameter, with nine gold electrodes for charge collection.

Collection Distance

Charge collection distance in CVD diamond
Charge collection distance plotted against applied voltage. Polycrystalline diamond grown using the CTS-6U reactor reached over 200 micron collection distance, exceeding electronic performance requirements for LHC detector grade material.

Particle and Radiation Detectors

CVD diamond is useful for radiation detector applications because it combines high radiation hardness, low leakage current, high carrier mobility, wide bandgap behavior, and thermal stability. Carat Systems has produced detector-grade polycrystalline diamond material with charge collection distance above 200 microns.

Gems Manufactured by a Carat Systems Customer

CVD diamond gems
0.5 and 1.3 ct gems grown from HPHT seeds using plasma CVD techniques. The bright yellow color in the 0.5 ct stone is generated from the embedded HPHT seed and grown over with CVD layers on both sides.
3 carat rough CVD diamond sample
A 3 ct rough CVD diamond sample.
CVD diamond gems cut from CTS grown diamond
Miscellaneous gems cut from CTS grown diamond, including fancy yellow princess cut, Asscher cut, and graded white brilliants.
