Current Transport Mechanism in Palladium Schottky Contact on Si-Based Freestanding GaN

Nanomaterials, 2020
In this study, the charge transport mechanism of Pd/Si-based FS-GaN Schottky diodes was investigated. A temperature-dependent current−voltage analysis revealed that the I-V characteristics of the diodes show a good rectifying behavior with a large ...

Thermionic emission current in a single barrier varactor [PDF]

From I-V measurements on Single Barrier Varactors (SBV) at different temperatures we concluded that thermionic emission across the barrier of the actual device is mainly due to transport through the X band.

Characteristics of Thermionic Emission from Emissive Oxides

JOURNAL OF THE ILLUMINATING ENGINEERING INSTITUTE OF JAPAN, 2008
Characteristics of thermionic emission from emissive oxides were investigated by using experimental data of work function measurement of commercial fluorescent lamp electrodes presented in our previous paper. Our aims are as follows: first, to reconfirm the difference in the expression of equations describing thermionic emission current density between
