Carbon nanotubes are an excellent choice for beyond-silicon nano-electronics due to their high mobility and low-cost processing. For advanced CNT electronics, fabrication of n-type behavior field effect transistors based on assembled aligned CNT arrays is required. We provide a reproducible method to produce n-type behavior FETs based on assembled aligned CNT arrays in this issue. High yields are obtained by combining the atomic layer deposition dielectric and metal contact engineering in an Air-stable and high-performance n-type type behavior. Determining transistor polarity, we also investigated the role of metal contacts and atomic layer deposition passivation in determining transistor polarity.

A theoretical investigation of resonant terahertz generation in an array of magnetized anharmonic carbon nanotubes is presented in this innovative framework. In the presence of an applied static magnetic field, two laser beams with frequencies and wavenumbers propagate through an array of vertically aligned anharmonic CNTs. It has been found that the application of magnetic field aids in the increase of the THz generation by increasing the nonlinearity of the unit. Dimensions, inter-tube separation, and the number of CNTs in THz have also been investigated.
