【 摘 要 】

We found out the general laws of the current-voltage characteristics hysteresis behavior for emitters of different nanomaterials - graphene, nanotube. Comparison of two power supply modes showed that the IVCs change with growth and decrease of the scanning voltage amplitude in "fast" mode which correlates with current-voltage characteristic hysteresis in "slow" mode. Common patterns forms of current-voltage characteristics in different power supply modes were identified.
