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 ...

You might have heard of electrets being used in microphones, but do you know what it is? Electrets produce a semi-permanent ...

Silicon transistors, which are used to amplify and switch signals, are a critical component in most electronic devices, from smartphones to automobiles. But silicon semiconductor technology is held ...

Aluminum foil is an indispensable item in nearly every household. It's versatile: You can use it for everything from foil packet recipes to cleaning your grill. The handy product comes equipped with a ...

MIT researchers have developed a new type of 3D transistor that could be more energy-efficient and powerful than current silicon-based transistors. The novel 3D transistors have been designed ...

Nanoscale 3D transistors made from ultrathin semiconductor materials can operate more efficiently than silicon-based devices, leveraging quantum mechanical properties to potentially enable ultra ...

Walter Brattain put a ribbon of gold foil around a plastic triangle ... The first point-contact transistor had been made. Telling the Brass For a week, the scientists kept their success a secret.

Some people wrap them in aluminum foil thinking they bake faster. Not only does it take the same amount of time to bake, you could unknowingly create a food safety risk. "Potatoes can potentially be ...

Why it matters: Silicon transistors are great, but just like any other object in the physical world, they are held back by a few limitations. The laws of physics put a bottleneck on performance ...

We won’t get foiled again. Americans think nothing of using aluminum foil to prepare breakfast, lunch and dinner — but there are some risks involved, according to food safety experts.
