摘要

在带Ti栅极的n型碳化硅器件上系统地测量了碳化硅肖特基二极管的低频过量噪声。噪声结果与这些器件的一般特性有关,如势垒高度和掺杂水平,从不同的温度测量中提取。1/f低频噪声与Kleinpenning(1979)提出的模型密切相关,因此最有可能是由于肖特基势垒耗尽区的迁移率波动。

Experimental investigation of noise sources in silicon carbide Schottky barriers
The excess low frequency noise of silicon carbide Schottky diodes has been systematically measured on n-type silicon carbide devices with Ti gate. The noise results have been related to general properties of these devices such as barrier height and doping level, extracted from varying temperature measurements. The 1/f low frequency noise closely follows a model proposed by Kleinpenning (1979) and is thus most probably due to mobility fluctuations in the depletion region of the Schottky barrier.
