“…To demonstrate circuit feasibility of InAs NW‐FETs, we have implemented a single balanced down‐conversion mixer using three gated NW devices ( M 1 , M 2 and M 3 ). Measured data show a low‐frequency voltage gain, G VC,low −f , of 6 dB, a 3 dB bandwidth (BW), f RF,BW−3 dB , of 2 GHz and a unity voltage gain at 5 GHz, adding further circuit capabilities for NWs [6–8].…”

An active single balanced down-conversion mixer is implemented using InAs nanowire metal oxide semiconductor field effect transistors (MOSFETs) as both active devices and passive resistive loads. Circuits with 6 dB low-frequency voltage gain and a 3 dB bandwidth of 2 GHz are measured for a DC power consumption of 3.8 mW from a 1.5 V supply. The circuits are fabricated using contacts made with 12 μmline-width optical lithography.

“…The positional control of small objects such as nanowires with a high degree of accuracy has been a challenge for practical applications of nanotechnology. In particular, the assembly of small objects on a substrate has been intensively investigated, and techniques using the Langmuir-Blodgett approach, 1,2) evaporation-induced assembly, 3,4) mechanical forces, [5][6][7][8] magnetic fields, 9,10) and electric field assist [11][12][13][14][15][16][17] have been reported. An approach using electric fields has a significant advantage in that small objects can be precisely aligned at predefined sites on a substrate.…”

In this study, we demonstrate the migration of Au colloids and silicon microrods in deionized (DI) water and isopropyl alcohol (IPA) by applying asymmetrical AC bias to two electrodes capped with a thin dielectric film. Both Au colloids and silicon microrods successfully migrate from one electrode to the other when asymmetrical AC bias is applied to the electrodes. Furthermore, the direction of the migration can be easily reversed by inverting the wave form. The insulated electrodes have the potential to prevent contamination and bubbling originating from electrochemical reactions, which makes the adoption of the technique for mass production processes easy and realistic. The bidirectional migration acts similarly to electrophoresis and is effective even in DI water and IPA in which conventional DC electrophoresis with insulated electrodes is ineffective. This technique is widely applicable to the positional control of small objects including nano- and micro-sized devices.

“…A typical configuration of electrodes is an electrode pair facing each other, and a rod-like nanomaterial such as a nanowire bridges the electrode pair by applying bias to the electrodes. [13][14][15][16][17]25) Owing to the positional accuracy and arbitrary property of electrode design, this technique has high affinity with integrated circuits or discrete circuits using nanowire devices.…”

In this paper, we demonstrate the orientation-controlled alignment of asymmetric Si microrods on a glass substrate with an asymmetric pair of electrodes. The Si microrods have the shape of a paddle with a blade and a shaft part, and the pair of electrodes consists of a narrow electrode and a wide electrode. By applying AC bias to the electrodes, the Si microrods suspended in a fluid align in such a way to settle across the electrode pair, and over 80% of the aligned Si microrods have an orientation with the blade and the shaft of the paddle on the wide and the narrow electrodes, respectively. When Si microrods have a shell of dielectric film and its thickness on the top face is thicker than that on the bottom face, 97.8% of the Si microrods are aligned with the top face facing upwards. This technique is useful for orientation-controlled alignment of nano- and microsized devices that have polarity or a distinction between the top and bottom faces.
