re: Triple-mode graphene transistors go analog

It is called ambipolar because it changes its behavior. It acts like a p-channel FET when the gate is at one polarity and an n-channel FET when the gate is at the other. So, it wanders ("ambi", think "amble" or like "ambidextrous") between polarities. What I am curious about is whether there is a dead band between polarities and is that controllable. I would also like to see a couple of simplified schematics using the device.

Life could become really interesting; does ambipolar therefore not need a substrate bias to prevent latchup? Could we discard our old 'nominal 0V' substrate and run everything in true differential? Every signal could have a mirror in the opposite polarity, giving potential for low crosstalk and low supply voltages/signal swings... could also make it easier to recycle charge locally instead of burning it in resistive losses.

It's probably called ambipolar to avoid confusion with bipolar as in BJT's, I guess(?)

Should it be called "bipolar" instead of "ambipolar"?


Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
