Nanowires were grown by metal-organic vapour-phase epitaxy (MOVPE) using the vapour-liquid-solid (VLS) growth mode. Metal-insulator field-effect transistors are fabricated using single n-InAs nanowire with a diameter of d = 50 nm as a channel and a silicon nitride gate dielectric. The gate length and gate dielectric variation are experimentally studied by means of DC output-and transfer-characteristics and is modeled using the long-channel MOSFET equations. The device properties are studied for an insulating layer thickness from 20 nm to 90 nm while the gate length is varied from 1 mum to 5 mum. The InAs nanowire field-effect transistors exhibit an excellent saturation behavior and breakdown voltage values of VBR > 3 V. The channel current divided by the diameter d of a nanowire reaches 3 A/mm. A maximum normalized transconductance gm/d > 2 S/mm at room temperature is routinely measured for devices with a gate length les 2 mum and a gate dielectric layer thickness les 30 nm. Based on Iniguez's continuous charge control model for surrounding-gate MOSFET, the device is modelled and compared to experimental data.
