Our hardware today is so proficient it is east to forget that we are still advancing. Most of the needs we can imagine have long since been well met.
Yet we ultimately want to power the Holodeck of Star Trek fame.
All our technology will ultimately migrate onto the graphene substrate technology that replace silicon chips. Clearly that means that nanotubes work naturally there. In the meantime it also integrates as well on the conventional structures as well...
Carbonics 100 GHz Wafer Scale Nanotube Technology Shows Nanotubes Can Finally Compete With Silicon

Carbonics has demonstrated a wafer-scalable approach for producing an array of aligned carbon nanotube (CNT) FETs with performance exceeding 100 GHz and linearity of 10dB.
This indicates we could finally be close to a tipping point where nanotubes become a serious competitor to silicon in almost all areas of microelectronics.
Wireless device technology operating in the millimeter-wave regime (30 to 300 GHz) increasingly needs to offer both high performance and a high level of integration with complementary metal–oxide–semiconductor (CMOS) technology. Aligned carbon nanotubes are proposed as an alternative to III–V technologies in such applications because of their highly linear signal amplification and compatibility with CMOS. Carbonics report the wafer-scalable fabrication of aligned carbon nanotube field-effect transistors operating at gigahertz frequencies. The devices have gate lengths of 110 nm and are capable, in distinct devices, of an extrinsic cutoff frequency and maximum frequency of oscillation of over 100 GHz, which surpasses the 90 GHz cutoff frequency of radio-frequency CMOS devices with gate lengths of 100 nm and is close to the performance of GaAs technology. Carbonic devices offer good linearity, with distinct devices capable of a peak output third-order intercept point of 26.5 dB when normalized to the 1 dB compression power, and 10.4 dB when normalized to d.c. power.
