Query: Frequency-tunable nano-oscillator based on Ovonic Threshold Switch (OTS)   Nano-oscillator devices are gaining more and more attention as a prerequisite
for developing novel energy-efficient computing systems based on coupled
oscillators. Here, we introduce a highly scalable, frequency-tunable
nano-oscillator consisting of one Ovonic threshold switch (OTS) and a
field-effect transistor (FET). It is presented that the proposed device shows
an oscillating behavior with a natural frequency (f_{nat}) adjustable from 0.5
to 2 MHz depending on the gate voltage applied to the FET. In addition, under a
small periodic input, it is observed that the oscillating frequency (f_{osc})
of the device is locked to the frequency (f_{in}) of the input when f_{in} ~
f_{nat}, demonstrating the so-called synchronization phenomenon. It also shows
the phase lock of the combined oscillator network using circuit simulation,
where the phase relation between the oscillators can be controlled by the
coupling strength. These results imply that the proposed device is promising
for applications in oscillator-based computing systems.
