Organic TFTs are shaking up the display world, offering flexible new design possibilities that challenge the long-standing ...

A new charge-coupled phototransistor merges static grayscale imaging and dynamic event detection into a compact, low-power ...

These home made transistors sacrifice a point contact diode to get the small chip of germanium, and form the other two electrodes with metal foil glued to paper. Given that germanium point contact ...
