    Im could be looking in billcos direction here :wink: but open to all

    Ive heard talk of a new transistor thats got fluorine added to it, all i know is its capable of 110GHz and is capable of letting chips operate at 11GHz but dont know how they work? what have they done? and whats the principle behind it?

    I had heard of this and had a quick read through, but mostly I have not kept up with electronics since about 1993.

    Basically imagine a wave in the water with a cork, the cork bobs up and down as the waves pass by, the bigger the cork the less it can respond to small waves passing. I know this sounds obvious but it is the limiting factor to transistors, the thinner you can make the middle slice the higher the frequency the device can be used at. Now read the article.
    THese are still Si Bipolar transistors though.

    To achieve the speed gain, researchers at the University of Southampton added fluorine to the silicon devices.

    I have I have something in my mind.

    Would anybody help me to figure out how to measure bjt transistor pins. Though in real life I think I don’t have to know the datasheet of it transistor.
