ABSTRACT

We developed the new theoretical model of terahertz waves nanodetector. The endohedral complex К+@C60 locates in the field of carbon nanotube (10, 10) and the fullerene C60 trimer retaining potential. This structure was obtained by experiment. The behavior of the considered system was simulated by quantum chemistry methods AIREBO and DFTB2 within the software KVAZAR. It is shown that the work of the nanodetector is determined by the by the frequency and the power of the incident electromagnetic wave. Under low power the complex К+@C60 oscillates in one of the potential wells. With the increasing of the incident radiation power К+@C60 starts to jump between potential well with terahertz frequency. At the same time there are critical values of power when the system loses stability and starts to destruct. Under 818 μW oscillations become disordered, and under 1 mW of considered hybrid compound destructs.
