Penn State University researchers have built a dual-gated graphene sensor that operates reliably in liquid environments, achieving up to 20 times greater signal sensitivity and 15 times less signal ...

Researchers have built working transistors from graphene nanoribbons less than a nanometer wide, achieving room-temperature switching performance that silicon struggles to match at similar scales. The ...

Editor’s note: This is part of a series called “The Day Tomorrow Began,” which explores the history of breakthroughs at UChicago. Learn more here. A field experiment is a research method that uses ...

On a physical level, a transistor’s internal functioning is very complex, but, in practice, using it in some simple experiments is quite easy and affordable for everyone. A transistor allows to create ...
