General characteristics of diamond
Diamond
has some of the most extreme physical properties of any material and is
the best semiconductor material ever known. Such properties as its
radiation and corrosion resistance, large bandgap, high electron and
hole mobility make it an attractive semiconductor for ionizing radiation
detectors. Diamond is chemically inert and has highest thermal
conductivity (5 times higher than copper). Diamond has the highest
radiation-damage level among radiation-detector semiconductor materials.
Low carbon nucleus charge, Z=6, provides tissue equivalence of diamond
detectors. Type IIa diamond is transparent over an extremely wide
spectral range.

Diamond Classification
Diamonds are classified depending on the amount of
nitrogen contained within material and whether it is held as an
interstitial or substitutional defect.
|
type Ia |
Nitrogen present up to levels of 4000¸
4500 ppm (0.3 wt %), incorporated in interstitial sites or
aggregates. |
|
type Ib |
500 ppm of nitrogen (0.06 wt %). Incorporated as
substitutional point defects. Most of synthetic diamonds are of
this type. |
|
type IIa |
Effectively free of nitrogen impurity. Very rare
in nature, these diamonds have enhanced optical and thermal
properties. |
|
type IIb |
Extremely rare in nature; p-type semiconductor
due to boron defects. |
