SEMICONDUCTOR DIODE

SEMICONDUCTOR DIODE

The semiconductor diode is formed by simply bringing an n- type and p- type materials together. At the instant the two materials joined together the electrons and holes in the region of junction will combine resulting in a lack of carriers in the region near the junction.

This region of uncovered positive and negative ions is called the depletion region due to the depletion carriers in this region.

There are three possible type of diode operating conditions. They are:

(a)  No bias

(b)  Forward biasing

(c)  Reverse biasing

NO BIAS

Under no-bias condition, any minority carriers in the n-type material that find themselves within the depletion region will pass directly into the p-type material. The closer the minority carrier is to the junction, the greater the attraction for the layer of negative ions and the less the opposition of positive ions in the depletion region of the n-type material. In the absence of an applied bias voltage, the net flow of charge in any one direction for a semiconductor diode is zero.

REVERSE BIAS

If an external potential V volts applied across the p-n junction such that the positive terminal is connected to the n-type material and negative terminal to the p-type material. The number of uncovered positive ions in the depletion region of the n-type material will increase due to the large number of free electrons drawn to the positive potential of the applied voltage. The net effect is the widening of the depletion region which will establish a great barrier to the majority carriers, effectively reducing the majority carrier flow to zero. However, number of minority carriers entering depletion region will not change, resulting in minority carrier flow. The current that exists under reverse bias conditions is called the reverse saturation current and is represented by Is.

Concepts Of Physics (Vol. 2) By H C Verma

Concepts Of Physics (Vol. 2) By H C Verma

Concepts Of Physics 

Concepts of Physics (Volume - 2) covers an exhaustive list of topics  that are necessary for a pre-college student. The book provides many examples and exercises based on these concepts, and these cater to students preparing for competitive exams, mainly those pertaining to the fields of engineering and medicine.

H C Verma’s Concepts of Physics is a comprehensive theoretical and conceptual guide that covers topics ranging from heat and temperature to semiconductor devices. The book starts with a chapter on Heat and Temperature and Kinetic Theory of Gases and explains the terminologies, units and problems that will be used through the course of the chapter.

Further, the laws of thermodynamics and heat transfer are explained before the subject moves towards concepts like electric field and potential. The same chapter covers topics like capacitors, Gauss’s Law and electric current in conductors. The subsequent chapters encompass topics like magnetic fields, permanent magnets, magnetic fields due to current, and electromagnetic waves. The final portion of the book explains the special theory of relativity. The book has two Appendix sections that provide an insight into the terminologies and definitions covered in the book.

Dr. Verma’s books are appreciated by students because of his detailed take on the subject and the wide range of numerical problems provided. The book serves as idealstudy material for competitive exams like IIT-JEE and other state level engineering exams.

About The Author
Dr. Verma is an Indian experimental physicist, educationist, lecturer and author in the field of nuclear science Apart from his research in areas of physics involving meteorites and EarthScience, he also gives lectures on topics like India’s heritage and cultural values.Concepts of Physics (Volume - 1) was Dr. Verma’s first book, and it was well received due to its comprehensive content. His other works include:

Quantum physics

• Foundation Science Physics

Dr. Harish Chandra Verma was awarded a doctoral degree at IIT-Kanpur. He began his career at Patna University as a lecturer and was then appointed as a reader. He’s currently employed at the department of Physics at IIT-Kanpur. Dr. Verma has also initiated personal endeavors for improving the Indian educational system. This can be seen through his ‘School Physics Project’ and ‘Shiksha Sopan’, a teaching institute that focuses on spreading knowledge among the underdeveloped sections around IIT-Kanpur.

what is JAVA

What Is Java?

Java is an object-oriented programming language developed by Sun Microsystems, a company

best known for its high-end Unix workstations. Modeled after C++, the Java language was

designed to be small, simple, and portable across platforms and operating systems, both at the

source and at the binary level (more about this later).

Java is often mentioned in the same breath as HotJava, a World Wide Web browser from Sun

like Netscape or Mosaic (see Figure 1.1). What makes HotJava different from most other

browsers is that, in addition to all its basic Web features, it can also download and play applets

on the reader’s system. Applets appear in a Web page much in the same way as images do, but

unlike images, applets are dynamic and interactive. Applets can be used to create animations,

figures, or areas that can respond to input from the reader, games, or other interactive effects on

the same Web pages among the text and graphics.

Although HotJava was the first World Wide Web browser to be able to play Java applets, Java

support is rapidly becoming available in other browsers. Netscape 2.0 provides support for Java

applets, and other browser developers have also announced support for Java in forthcoming

products.

IMAGE IMPEDANCE

image impedance

Image impedance is a concept used in electronic network design and analysis and most especially in filter design. The term image impedance applies to the impedance seen looking in to the ports of a network. Usually a two-port network is implied but the concept is capable of being extended to networks with more than two ports. The definition of image impedance for a two-port network is the impedance, Z_i 1, seen looking in to port 1 when port 2 is terminated with the image impedance, Z_i 2, for port 2. In general, the image impedances of ports 1 and 2 will not be equal unless the network is symmetrical (or anti-symmetrical) with respect to the ports.
