| titleOfInvention | Low donor concentration zinc oxide and devices utilizing same |
| abstract | EFFECTIVE OPERATION OF ACOUSTOELECTRIC DEVICES SUCH AS AMPLIFIERS, OSCILLATORS, CIRCULATORS, ISOLATORS AND SWITCHES REQUIRES HIGH RESISTIVITY SUBSTANTIALLY UNCOMPENSATED MATERIAL. UNCOMPENSATED ZINC OXIDE, OTHERWISE CONSIDERED THE BEST MATERIAL FOR SUCH DEVICES, HAS BEEN UNSUITABLE BY REASON OF ITS LARGE DONOR CONCENTRATION. SUBSTANTIALLY UNCOMPENSATED MATERIAL MAY NOW BE PREPARED BY A TECHNIQUE INVOLVING INTRODUCTION OF (1) LITHIUM DURING HYDROTHERMAL GROWTH, (2) REPLACEMENT OF LITHIUM BY ZINC BY HEATING IN ZINC VAPOR; AND (3) OUT-DIFFUSION OF INTERSTITIAL ZINC BY BAKING IN OXYGEN. |
