Gallium Oxide: Semiconductor material with improved Heat conductivity

semiconductor device bandgap image

According to the recent work by Flosfia, a start-up in Kyoto, gallium oxide is one of the best semiconductor material with improved heat conductivity. The electronic component made from these type of material easily passes the electricity through power supplies, inverters etc are cheap and capable of handling high voltages. For the movement of electrons from the valence band to the conduction band, bandgap plays a vital role. Gallium oxide devices have approximately 5eV bandgap higher than that of silicon carbide ( 3.3 eV ) or gallium nitride (3.4 eV) which makes it more efficient. Due to the higher band Read More …

Rectifiers Basics, Types and Comparison

Rectifier image

A rectifier is an electrical device consist of one or more diodes allows the flow of current only in one direction. It basically converts alternating current into direct current. Rectifiers can be mould in several forms as per requirement like semiconductor diodes, silicon controlled rectifiers, mercury arc valves, vacuum tube diodes etc. In our previous articles, we explain diodes,  types of diodes in detail. In this article, we are going to explain rectifiers, rectifier circuits, applications etc. For signal detection and power rectification, diode rectifier circuits are widely used in electronic circuit design. These are used in various devices includes radio Read More …

Diode: Types, operation and Symbols [Guide]

Diodes image

Diode is an electronic device conduct current in one direction i.e. either in the forward direction or in the reverse direction. Today’s most commonly used diode is semiconductor diode. In our previous articles, we explain basic theory of semiconductors, P-n junction diode, and P-n junction diode characteristics etc. Here we are going to explain about Diodes and its types. Diode Basics: It is a specialized component with two electrodes i.e. anode and cathode and has high resistance to the flow of the current in one direction & low resistance in the other direction. Diodes can be used as oscillators, rectifiers, signal Read More …

p type 2d material image

Great magic done by the Ashutosh Tiwari and his team, have discovered first stable p-type 2D semiconductor material at the University of Utah that opens the door for much speedier smartphones and computers. The semiconductor made of the element tin and oxygen, tin monoxide ( SnO) is a layer of 2D material only one atom thick, allows electrical charges like electrons to move through it at a faster speed than conventional 3D material such as silicon, germanium etc. [Photo:Dan Hixson/University of Utah College of Engineering] Researchers in the field of engineering materials have discovered that new types of 2D material such Read More …

PN junction Diode Characteristics and Biasing

Pn junction is one of the most important structures in today’s semiconductor technology used in transistors, FET and many types of integrated circuits. In our previous articles, we have seen  p-n junction formation from a p-type and n-type semiconductor and Semiconductor electronics. We have also learned about diffusion current, drift current and depletion region. Here we are going to explain how p-n junction diode characteristics. [Image source] P-n junction diode: To understand the behavior of p-n junction we make it conducting by applying an external voltage over a range of 0v, 5v, 10v and determine how the current passed through Read More …

Pn Junction : Basic theory

formation of pn junction image

Pn junctions are formed by joining two different type of semiconductor material i.e. p-type semiconductor on one side and n-type semiconductor on another side. In this article, we are going to explain you about p-n juenction formation, phenomena of p-n junction formation and basic equations. Have a look at it. It is discovered by the American physicist Russell Ohl at Bell laboratories. In p-type semiconductor holes are majority carriers and electrons are minority carriers while in n-type semiconductor electrons are majority carriers and holes are minority carriers i.e. one end has excess of electrons and other has excess of holes. P-n Read More …
