DEFINITION

Classification: 420/903

SEMICONDUCTIVE:

Cross-reference art collection alloys, or metallic composition whose resistivity at room temperature is in the range of 10[supscrpt]-2[end supscrpt] to 10[supscrpt]-9[end supscrpt] ohm-cm (which is between the range of metallic conductors and insulators).

(1) Note. These compositions are usually employed in barrier layer devices, e.g., transistors, etc.
