| 31. | High-purity germanium ( HPGe ) detectors typically have higher sensitivity.
|
| 32. | The germanium isotope emits two weak gamma rays and a conversion electron.
|
| 33. | Appreciable gallium and germanium may also be incorporated into the crystal structure.
|
| 34. | Early investigations into low bandgap semiconductors focused on germanium ( Ge ).
|
| 35. | Similar structures have been found with silicon, germanium or arsenic heteroatoms.
|
| 36. | Common semiconductor materials include silicon, germanium and gallium arsenide.
|
| 37. | P-type point contact ( PPC ) germanium detectors are used.
|
| 38. | That time the production of germanium was classified as a secret one.
|
| 39. | Germanium is usually considered to be a metalloid rather than a metal.
|
| 40. | Germanium can be derived from certain minerals and from the ashes of coal.
