It's called a diode because the device has two terminals. Devices that have three terminals are called triodes, and those with five pentodes. Words of that type have fallen by the wayside except in the realm of vacuum tube electronics ... except for the word diode, which has hung on. Note that the Wikipedia article that you cite refers specifically to ...


The negative differential resistance creates a special phenomena: under a certain bias and certain incident electron energies, the transmission function through the double barrier is nearly zero. In other words, for a finite voltage domain, the current is nearly zero, i.e. a rectifying behaviour. This can be referred to as "generalized diode", since the ...


The answer is "maybe" and you will not know which one to adjust, if any, without a circuit diagram. Just record their positions so you can undo any changes you make, and experiment. As you said - it's cheap.
