  • This simple animation video clearly explains the topics P-N junction semi conductor or diode, what is forward bias and reverse bias, what is diffusion current and drift current, what is avalanche breakdown etc

    What is a P — N junction semiconductor and how is it formed?

    The PN junction semi conductor is a combination of P type semiconductor with N type semiconductor to achieve the practical utility of both. It’s formed, when a P type semi conductor is joined to an N type semiconductor.

    The P type semiconductor has free holes with positive charged and the N type semiconductor has free electrons with negatively charge.

    What happens when a PN junction is made?

    When P and N semiconductors are joined to make the PN junction semiconductor diode, the electrons near the PN junction jump from N to P and holes near the junction jump from P to N. This phenomenon creates a space charge region or a depletion layer as shown in the video. At this space charge region due to the movement we have electrons in P region and holes in N region. For some time the electrons move back from P to N in the space region or depletion layer and some holes move back from N to P in the space region. This continues to happen till equilibrium is reached. This movement of electrons and holes in the space region or diffusion layer gives rise to Diffusion current.

    What is Forward bias and how does it occur?

    Forward bias occurs when the positive terminal of battery is connected to the P region and the negative terminal of battery is connected to the N region. In this condition what happens is the positive terminal repels the holes towards the junction and the negative terminal repels the electrons towards the junction. Due to this repulsion, the depletion region or space region narrows down as shown in the video.

    But at a particular condition, If the voltage in the forward bias is above a specified range, the electrons in the N region drifts through the junction and migrates to the P region and the holes in the P region drifts through the junction and migrates to the N region.

    Now the current flows across the circuit and this current are called the Drift current.

    What is Reverse bias and how does it occur?

    Reverse bias occurs when the negative terminal of the battery is connected with the N region and positive terminal with the P region. In this condition holes (positively charged) from the P region get attracted to the negative terminal of the battery and electrons (negatively charged) get attracted to the positive terminal of the battery. This results in the depletion layer to widen up.

    Now the PN junction acts as an insulator and will not allow any current to flow in the circuit. But at a condition, if the battery voltage is above a particular limit, which is called as the reverse bias breakdown voltage level. Electrons and the holes breakdown through the PN junction and cross over resulting in the current to flow through the circuit. This break down is called avalanche breakdown

    In this process the current flowing through the PN junction is very high and ultimately the PN junction gets damaged due to overheating caused by the excess flow of current.
    This is how a PN junction semiconductor works.

    Things you will need:
    - Stock tank (size of your choosing- ours is 8 ft.)
    - Above Ground Pool Pump
    - Weatherproof Silicone Sealant
    - Hole Saw with Arbor
    - Plunger Valves
    - Pool Outlet
    - 1-3 Rubber Washers (or Gaskets)
    - 1 Strainer Nut

    Other things you will need for maintenance:
    - Chlorine Tablets
    - Floating Pool Dispenser
    - Water Testing Kit

    Step 1- Find a nice level area to lay the stock tank on. If the area where you have chosen isn’t level, use sand or rocks to build up whatever side needs it. It is very important that your stock tank be level so there aren’t any unexpected leaks.
    Step 2- Cut holes in your stock tank. I’m not going to lie- this is a pain in the butt. We bought a hole saw with an arbor and it took two people to get through the metal. You will need two holes, one at the top and one at the bottom. In an above ground pool, these aren’t usually right on top of each other, but ours are. We haven’t ever seen this as a problem.
    Step 3- Start assembling the parts. In the pool pump package there is a packet with instructions, warnings and troubleshooting. This packet proved to be vital in the setup of the pool. I did end up getting 2 gaskets for the bottom section (the drain section), one for the inside of the pool and one for the outside. It only says you need one for the inside, but this was causing a drip for us. I also put thread seal tape around the connections that were closest to the pool. There are a lot of connections, and each one has a gasket, so you could probably get away without the tape. I didn’t put it on all the connections, the only ones that really seemed to matter were the ones that are connecting the hoses to the pool.
    Step 4- Apply silicone waterproof sealant around all crevices involving the input and output parts. I did this on the inside of the pool and the outside. And I applied it VERY HEAVILY and did two layers, allowing one to dry before the second was applied. Sealing these crevices is one of the most important parts. This is what is going to keep the water in the pool. Well all of these steps are leading up to keeping water in the pool, but if there is any chance that it’s going to be getting out, this is what will save you.
    Step 5- Test for leaks. Before I added water to the pool, I took a water bottle and poured a good amount of water on the input and output parts. You could also just use a water hose. I would make sure the hose wasn’t on full blast. You don’t want to accidentally penetrate the sealant.
    Step 6- Once you are sure there aren’t any leaks, fill the pool just above the bottom hole/output. Check again to see if any leaks have started. If there aren’t any, fill the rest of the pool up!
    Step 7- Turn the pump on. Make sure both plunger valves are open/unlocked. When you first do this water may not come out of the output, but there is a solution! Twist off the knob on top of the filter pump to let some air out. Some water may escape too and that’s okay, just be ready to screw it back on as soon as the water starts coming out.
