Although waiting for the hat-trick this year, it is not
achieved without scoring confirming the 2nd goal and that happened
with your paper being accepted by pss-RRL!

We demonstrate a new Thin Film Transistor (TFT) architecture
that allows expansion of the device width using continuous fin features –
termed as wavy channel (WC) architecture. This architecture allows expansion of
transistor width in a direction perpendicular to the substrate, thus not
consuming extra chip area, achieving area efficiency. The devices have shown
for a 13% increase in the device width resulting in a maximum 2.5× increase in ‘ON’
current value of the WCTFT, when compared to planar devices consuming the same
chip area, while using atomic layer deposition based zinc oxide (ZnO) as the
channel material. The WCTFT devices also maintain similar ‘OFF’ current value,
~100 pA, when compared to planar devices, thus not compromising on power
consumption for performance which usually happens with larger width devices.
This work offers an interesting opportunity to use WCTFTs as backplane
circuitry for large-area high-resolution display applications.
Congrats!
