Abstract The ballistic transport of electrons and unique structural characteristics of graphene and carbon nanotubes enable them to play an important role in nano electronical appliances. Nanodevices based on carbon nano materials can further reduce device size without affecting performance. Here, this paper analyzes Fin Field-effect transistor (FinFET) and Tunnel Field-effect transistor (TFET) based on graphene nanoribbon (GNR) and carbon nanotube which could be used for reducing power consumption. Then it summarizes the applications of graphene in micro/nano sensors based on the electrical, mechanical, optical, and thermal properties of graphene. Graphene’s single-atom thickness and charge storage mechanism provide itself with great potential in the field of resistive memory. Graphene is also widely used in flexible electronic devices.

A 16-nm-Lg p-type Gate-all-around (GAA) silicon nanowire (Si NW) metal oxide semiconductor field effect transistor (MOSFET) was fabricated based on the mainstream bulk fin field-effect transistor (FinFET) technology. The temperature dependence of electrical characteristics for normal MOSFET as well as the quantum transport at cryogenic has been investigated systematically. We demonstrate a good gate-control ability and body effect immunity at cryogenic for the GAA Si NW MOSFETs and observe the transport of two-fold degenerate hole sub-bands in the nanowire (110) channel direction sub-band structure experimentally. In addition, the pronounced ballistic transport characteristics were demonstrated in the GAA Si NW MOSFET. Due to the existence of spacers for the typical MOSFET, the quantum interference was also successfully achieved at lower bias.

Phosphorene, a new two-dimensional semiconductor, with its outstanding electro-optical and transport features has been studied extremely in recent years. However, the modeling of its interesting properties needs to be explored in more details. In this paper, an analytical model for conductance variations in the proposed phosphorene based field effect transistor is presented based on phosphorene energy dispersion relation and a tunable behaviour due to the alteration of gate voltage is reported. Moreover, the current–voltage characteristic of the phosphorene based nano device has been analyzed theoretically and an acceptable ION/IOFF ratio about 105 is calculated for different bias values. In addition, data from the suggested current model is compared with the extracted experimental data which shows good agreement and confirms the validity of the suggested model in a desirable manner. Hence, it should be noted that the outcome of this paper can be extremely useful in the analysis of phosphorene based nano devices especially nano-sensors.
