Using two self-healing transistors and a load resistor, NAND and NOR logic gates were assembled, and their logic states were reliably maintained under 20% tensile strain. Moreover, the preassembled ...

In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...
