polycrystalline diamond optics working in the sphere, so now it is probable to say that an absorption coefficient of all-around

Equally, each time a ample amount of electrons are provided to saturate area dangling bonds, it can be inferred that progress level reaches a plateau. The diminished deposition level of diamond at larger levels of nitrogen doping (1.5% for S5) is usually ascribed to extreme unpaired electrons provided by substitutional nitrogen, which appreciably dehydrogenates the expanding surface and leads to an extra of adjacent unsaturated bonds; In the meantime, inadequate bonding with the hydrocarbon development precursor happens.

For that reason, the diamond area’s suspended bonds collapse and undertake a transformation into graphite bonds, which can deteriorate the crystalline quality from the diamond. Additionally, due to the substantial bond Power of carbon and nitrogen, desorbing nitrogen atoms from CN bonds to the surface area to produce new expansion web pages gets to be even tougher when compared to CH bonds [29]. These things collectively impede even more blend with diamond growth precursor, describing why an increased N2 gas combination ratio doesn't often increase significant-level expansion and why You will find there's saturation during the deposited rate of SCDs.
