研究了正向偏置下多壁碳纳米管在10 Hz-10 kHz频率范围内的室温噪声特性。对单个多壁碳纳米管(1 mW)和两个交叉多壁碳纳米管(2 cmW)进行了噪声测量。在1 mW中发现的过量噪声始终是1/f类的。然而,2 连续波表现出较高的噪声水平,并且噪声谱具有不寻常的电流依赖性。2 连续波噪声的主要来源是扩散噪声。
The noise properties at room temperature of multiwalled carbon nanotubes under forward bias, for frequencies between 10 Hz–10 kHz, have been investigated. The noise measurements were made for one individual multiwalled carbon nanotube (1 MW) and two crossing multiwalled carbon nanotubes (2 CMW). The excess noise found in 1 MW is consistently 1/f-like. However, 2 CMW shows higher noise level, and the noise spectrum has an unusual dependence on the current. The main origin of noise in 2 CMW was attributed to the diffusion noise.
