| titleOfInvention | Method for detecting concentration of high-purity germanium polycrystal carrier |
| abstract | The invention discloses a method for detecting the concentration of a high-purity germanium polycrystal carrier, which comprises the steps of cooling a germanium ingot to a specified temperature and then detecting resistivity, wherein the result is stable and accurate; the ultra-high pure germanium polycrystal regions of the germanium of n and p are separated, and when the ultra-high pure germanium single crystal is prepared, the required n and p type ultra-high pure germanium single crystal can be prepared by adjusting the proportion of the n and p type charge amount of the ultra-high pure germanium polycrystal; the low-temperature resistivity is measured firstly, and then the Hall sample wafer is taken for Hall detection, so that the Hall sample wafer can be prepared accurately, the wafer taking times of the Hall sample wafer can be reduced, and the waste of qualified germanium sections can be avoided. |
