Summary, in English

Semiconductor devices are heavily dependent on dopant incorporation in order to control the electrical properties. In this paper we investigate the possibility of using gates wrapped around a nanowire (NW) channel as a way of tuning the Fermi level position, in certain cases removing the need for dopants and providing a more dynamical way of setting the device properties. InP NW devices with omega gates are fabricated, and a p-n junction is formed in a nominally intrinsic NW channel. In order to further increase the electrostatic control of the channel and other device properties, vertical devices are discussed as a promising way of implementing this type of device.
