纳米机电二极管中的直接机械混合

Direct mechanical mixing in a nanoelectromechanical diode

Hyun S. Kim, Hua Qin, Robert H. Blick

摘要:

我们观察到直接机械混合在纳米机电晶体管制造的半导体材料中工作在射频频带10-1000兆赫。该器件由长度为240 nm、直径为50 nm的机械柔性柱制成,放置在阻抗匹配的共面波导中的两个电极之间。我们发现了非线性IV特性,它能够通过纳米机械晶体管实现两个电磁信号的射频混合。该混频器的潜在应用是需要高吞吐量绝缘的通信电子电路中的超灵敏位移检测或信号处理。

英文摘要:

We observe direct mechanical mixing in nanoelectromechanical transistors fabricated in semiconductor materials operating in the radio frequency band of 10-1000 MHz. The device is made of a mechanically flexible pillar with a length of 240 nm and a diameter of 50 nm, placed between two electrodes in an impedance matched coplanar wave guide. We find a non-linear IV-characteristic, which enables radio frequency mixing of two electromagnetic signals via the nanomechanical transistor. Potential applications for this mixer are ultrasensitive displacement detection or signal processing in communication electronic circuits requiring high-throughput insulation.
