摘要：
A complex investigation of the structure and emission characteristics of linear-chain carbon is accomplished. This material is demonstrated to be stable at high temperature (700 degrees C), and the thermal emission is shown to be governed by the Schottky mechanism with the material characteristics reaching record-breaking values: an emission threshold of 800 V/mm and a thermoionic work function of 0.43 eV. These values are found to arise during sp(1) carbon crystallization and vanish after its graphitization. The very low value of the work function of linear-chain carbon is theoretically substantiated.
