Flared, dog-bone layout for sub-nm 2D transistors drastically lowers electrical contact resistance that limits performance at atomic scales

"atomic scale rectangular nanoribbon transistors exhibit contact resistance where metal leads meet thin channel, degrading electrical current limiting performance... overcome widening contact regions at ends while keeping central channel ultra-narrow... maintains high-velocity carrier injection/ energy efficiency as post-silicon 2D semiconductor dimensions continue scaling downward under Moore's Law... enables carrying significantly higher current densities without experiencing typical miniaturization bottlenecks"
