Which diodes has a characteristic curve with both a forward and a reverse breakover?
Schottky
What type of diode exhibits negative resistance?
A Tunneldiode, usually made of GaAS. In a part of its curve it has a negative resistance. This means that when you increase the voltage in that region, the current will drop.
Why the alternator do not operate near the knee of its saturation curve?
Actually, alternators (synchronous generators in other parlance) are normally operated slightly saturated by design. If they were operated completely unsaturated, the machine is not being used to its full capability. We don't attempt to operate them beyond the knee, because the losses increase significantly, and the output voltage & current are distorted. It is important to note that there are two different windings to consider when discussing saturation. The DC field (rotor) winding is usually operated somewhat in the saturated region. The AC armature (stator) winding is operated near - but below - the knee to avoid output distortion.
What is the zener region?
The zener region describes the area on the performance curve (a graph of voltage across versus current through the junction) of a zener diode. The diode acts like a "regular" diode in the forward biased direction. When some 0.7 volts or so is reached, forward current begins to climb rapidly as voltage is increased (for silicon diodes.) But in the reverse direction recall that as the diode is reverse biased, a small amount of current will flow (because of minority carriers). This "trickle" of current will continue until the "zener voltage" is reached, and then the diode will begin to conduct heavily. On the graph, this is the zener region. Zener diodes can be made to breakdown at a specific voltage, and their ability to conduct reverse current can be increased by manufacturing a larger diode. That means there are a range of voltages and wattages of zener diodes available. Wikipedia has more information and that graph. Use the link provided to get there.
What is LED characteristics curve?
A: Any device whether it be diode, led, scr, triac and so forth has characteristic of current/voltage behaviour as these I/v are varied

What is the characteristic shape of logistic growth curve?
The classic "S" shaped curve that is characteristic of logistic growth.
The characteristics curve of the component?
This is probably the I-V characteristic: Apply a voltage to one terminal of the component, the current through the component is then recorded; this is done for varying values, and is plotted out on a graph. For transistors, this shows where the "linear operation" region is; for diodes, this shows the "turn on" voltage. Such characteristics will be in the data sheets for whatever component you're using.
What type of diode exhibits negative resistance?
A Tunneldiode, usually made of GaAS. In a part of its curve it has a negative resistance. This means that when you increase the voltage in that region, the current will drop.
What is the toe region of a curve?

What two variables are plotted on a collector characteristic curve?

How the voltagedrope can be understand in the circuite of and gate using diodes?
A diode while forward conducting follows an exponential curve depending on the current trough. In designing diodes gates it is safe to assume a voltage drop of 0.6volts for each diodes even in a ternary level.
