摘要
In this work, the low-frequency noise (LFN) characteristics of the 3-terminal n-type gated Schottky diode (GSD) were investigated. The GSD shows the 1/f noise behavior, and the noise origin depends on the operating current (I-D) of the GSD. The 1/f noise is mainly generated by the barrier height fluctuation near the metal-semiconductor interface at the reverse Schottky diode (SD) in the low I-D region, and by the carrier number fluctuation (CNF) at the n-type FET in the high I-D region. The LFN characteristics in the low I-D region are strongly affected by the temperature. With increasing temperature, the transition of the 1/f noise origin from the reverse SD to the n-type FET occurs at lower I-D.
