of the mayenite-type collector layer a material having a work function as a thin 0.5 electron volts and about 1.5 electron volts to. With its low work function of the emitter has a very low thermal conductivity at the same time about 23 to 45 mW/cm by degrees on. The collector layer consists of intermetallic compounds of the rare earth elements, aluminides

or rare earth metal, wherein the rare earth metals may be substituted in part by strontium or barium with phosphorus or arsenic doped n-type diamond films or from, the oppose the entry of electrons a particularly low resistance. 0.01 to 10 micrometers The thickness of the collector layer is located between. The emitter can be up to several millimeters thick. Thermoelectric and thermionic effects is in addition. The arrangement can be used also for generating temperature differences by applying a DC voltage. |
