General characteristics of Diamonds
|
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. |
