However, the Zener Diode or “Breakdown Diode”, as they are sometimes referred too, are basically the same as the standard PN junction diode but they are specially designed to have a low and specified Reverse Breakdown Voltage which takes advantage of any reverse voltage applied to it. The Zener diode behaves just like a normal general-purpose diode consisting of a silicon PN junction and when biased in the forward direction, that is Anode positive with respect to its Cathode, it behaves just like

An avalanche diode is a special type of semiconductor device designed to operate in reverse breakdown region. Avalanche diodes are used as relief valves (a type of valve used to control the pressure in a system) to protect electrical systems from excess voltages. Construction of avalanche diode Avalanche diodes are generally made from silicon or other semiconductor materials. The construction of avalanche diode is similar to zener diode except the doping level in avalanche diode differs from zener

Applications of Diodes A diode is a two terminal device, widely used in the field of electronics. The smallest of circuits, to the largest, have diodes in them, in one form or the other. The function of the diodes can be explained by using an analogy of an air pump, which only allows the flow of air in one direction. Similarly a diode only allows the circuit to pass current through in one direction; this is done in two conditions. The conditions are a) Forward Bias or b) Reverse Bias Forward

Relevant Theory/Background Information (Heading, Level 2) Experiment 2 : Diodes are basic semiconductor devices that will only allow current to flow through them in one direction only, Forward bias. Diodes are made from two differently doped layers of semiconductor material that form a PN junction. When the diode is reverse biased, the positive holes are attracted towards the negative voltage and away from the junction. Likewise the negative electrons are attracted away from the junction towards

(zdnet.com). There is a technology being developed in research labs around the world that could change all this (Ibm.com). It?s called an OLED display, and it could truly change the way we look at technology. OLED stands for Organic Light Emitting Diode, sometime they are referred to as Organic Light Emitting Devices. OLED?s are made from an organic material that has luminescent properties that glows when voltage passes through it. They operate on the principle of converting electrical energy into

devices used in different applications of power conversion. The diode is one of the oldest semiconductors devices and is still wildly used today in power electronics. Diodes are found in virtually all power converts in one form or another. For this reason our discussion will be focused on the application of power diodes. Power Diodes are two terminal electronic devices that permit current flow in predominantly one direction. Diodes are composed of differently doped silicon or germanium bounded

Organic (Polymer) PV Cells With the global demand for electricity ever increasing, the only way to tackle the issue is to harness energy from renewable sources. An exciting new technology which can be helpful in addressing this issue is the organic PV cells. Organic solar cells can be coloured, flexible and transparent. What is interesting to note is that they can even generate electricity under cloudy skies. With the development of these cells, sooner rather than later we will be able to harness

Physics 52: Lab #2 Oscilloscope and Diodes Ziyu Liao 8/31/15 Honor Code Pledge: In this lab, we were introduced to the Oscilloscope and Diodes. In first part of this lab we continued our exploration of the current, resistance, voltage, and the breadboard. In the first part, I tested the resistance of multiple people, build a parallel circuit, measured the effects of a parallel circuit on current, and explored the characteristics of a diode. In the second part of the lab, I was introduced the Oscilloscope

Semiconductors were being studied in laboratories as early as the 1830's. The materials were usually poor conductors if heated and often carried photoelectric properties. (Electrical production by shining light on the material.) Soon, this property of changing conductivity would become of vital importance to the world of electronics and communications. (Micron) Common semiconductors include silicon, zinc and germanium; however, silicon is by far the most widely implemented due to its abundance. Also

In the modern world, we have many devices that help us with our daily lives. These devices include the cellular phone, the music player and many more but none of these devices would exist without the invention of the transistor. The transistor is essentially the most important device ever created. Not because of what it does but because of what size it is. The transistor is absolutely necessary for our day-to-day lives. The transistor was invented by a man by the name of John Bardeen. He invented
