Abstract

Unlike junctions in solid-state devices, a plasma-metal junction (pm-junction) is a junction of classical and quantum electrons. The plasma electrons are Maxwellian in nature, while metal electrons obey the Fermi-Dirac distribution. In this experiment, the current-voltage characteristics of solid-state devices that form homo or hetero-junction are compared to the pm-junction. Observation shows that the turn-on voltage for pn-junction is 0.5V and decreases to 0.24V for metal-semiconductor junction. However, the pm-junction's turn-on voltage was lowered to a negative value of

- 7.0 V

. The devices with negative turn-on voltage are suitable for high-frequency operations. Further, observations show that the current-voltage characteristics of the pm-junction depend on the metal's work function, and the turn-on voltage remains unchanged. This result validates the applicability of the energy-band model for the pm-junction. We present a perspective metal-oxide-plasma (MOP), a gaseous electronic device, as an alternative to metal-oxide-semiconductor (MOS), based on the new basic understanding developed.

等离子体-金属结：具有负开启电压的结

与固态设备中的结不同，等离子体-金属结（pm-结）是经典电子和量子电子的结。等离子体电子的性质是麦克斯韦电子，而金属电子则服从费米-狄拉克分布。在本实验中，形成同结或异结的固态器件的电流-电压特性与 pm 结进行了比较。观察结果表明，pn 结的开启电压为 0.5V，而金属半导体结的开启电压则降至 0.24V。然而，pm 结的开启电压却降低到了负值 -7.0V。具有负开启电压的器件适用于高频操作。此外，观察结果表明，pm 结的电流-电压特性取决于金属的功函数，而开启电压保持不变。这一结果验证了能带模型对 pm 结的适用性。基于新的基本认识，我们提出了金属-氧化物-等离子体（MOP）这一气态电子器件，作为金属-氧化物-半导体（MOS）的替代品。
