What is a slogan that has the element indium?
Indium, a element of the new mulennium. -B.P.R
Is indium name after India?
No, it is named from the blue (indigo) lines in its spectrum.
Is indium the strongest mineral?
No, maybe for elements but not for minerals, the strongest mineral is diamond.
What is the meaning of semiconductors?
Oversimplifying it significantly "not quite conductors". These are materials whose ability to conduct electricity is between conductors and insulators but can be very precisely controlled by doping with other elements as impurities, allowing the construction of electronic devices that can: control the direction of current flow, amplify signals, act as switches, perform boolean logic functions, etc. These materials can be classed as elemental semiconductors, binary semiconductors, other semiconductors. The elemental semiconductors are elements with 4 valence electrons that are not metals (e.g. silicon, germanium), the binary semiconductors are "alloys" of two elements: one with 3 valence electrons and the other with 5 valence electrons (e.g. gallium arsenide, indium phosphide), other semiconductors can be elements (e.g. selenium) compounds (e.g. galena, copper oxide) or complex "alloys" of several elements (e.g. gallium arsenide phosphide, aluminum gallium indium phosphide). The term semiconductors is also used to refer to the electronic devices mades of these materials.
How does a light emitting diode work?
Light Emitting Diodes, commonly called LED's, do dozens of different jobs and are found in all kinds of devices. Among other things, they form the numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on. Collected together, they can form images on a jumbo TV screen or illuminate a traffic light. :)Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescents, they don't have a filament that will burn out, and they don't get especially hot. They are illuminated solely by the movement of electrons in a material, and they last just as long as a standard transistor. Hope this helped.That talks only about usage, which is all well and good but totally fails to answer the original question of how. Also incandescents operate "solely by the movement of electrons in a material", so that is not really a difference; the difference is in the way those electrons move.LEDs are ordinary semiconductor diodes, except that they are made of different semiconductors than silicon or germanium. Semiconductors composed of multiple elements that by themselves are not semiconductors (e.g. Aluminum gallium indium phosphide = AlGaInP for red, Indium gallium nitride/Gallium(III) nitride = InGaN/GaN for green, Indium gallium nitride = InGaN for blue). Such semiconductors are different from silicon and germanium in 2 ways:larger bandgap between conduction and valence energy bandstransparency to visible light; both silicon and germanium are opaqueThe larger bandgap of these semiconductors means that when electrons and holes combine at the junction they release enough energy to produce photons of light, not just phonons which only vibrate the crystal atoms and cause heating as in silicon and germanium with their smaller bandgap. This larger bandgap also means that the forward bias voltage is larger (between ~1V to ~5V depending on material vs. 0.7V for silicon or 0.2V for germanium).The transparency of these semiconductors allows the photons once generated to escape from the material and be seen, instead of being immediately absorbed as they would in an opaque material and cause heating only.Going back to the difference in operation between incandescents and LEDs:the movement of electrons through the filament of an incandescent light bulb is a phenomenon explained in classical physics, this movement is continuous and causes resistance heating making the filament hot enough to glowthe movement of electrons (and holes) at the junction in an LED is a phenomenon explained in quantum mechanics, this movement is a sudden jump between energy levels in atoms and directly produces light photons
What kind of semiconductor is produced by adding indium in semiconductor crystals pnp or npn?
pnp
IS indium a p type semiconductor?
No, indium is not a p-type semiconductor on its own. Indium is typically used as a dopant in semiconductors to tune their electrical properties, such as increasing the conductivity or modifying the bandgap.
What does the Indium Corporation do?
Indium Corporation supplies soldering materials to electronics, semiconductor, solar and thin film markets. They develop and manufacture materials used in the electronics assembly.
How is a semiconductor made p-type?
by doping it with p-type impurities: boron, aluminum, gallium, indium; that have 3 valence electrons.

Draw the table of semiconductor elements?
Sure, here is a concise table of common semiconductor elements: Silicon (Si): Widely used in electronic devices due to its abundance and semiconductor properties. Germanium (Ge): Another commonly used semiconductor with properties similar to silicon. Gallium (Ga): Used in specialized devices like LEDs and solar cells. Indium (In): Often used in combination with gallium to create indium gallium arsenide (InGaAs) for high-speed electronics. Arsenic (As): Combined with other elements to create semiconductor materials like gallium arsenide (GaAs) for high-frequency applications.
Diffrentiate n-type and p-type?
When pentavalent impurity is added to pure semiconductor, it is known as N-Type semiconductor. In N-type semiconductor electrons are majority carriers where as holes are minority carriers. impurities such as Arsenic, antimony are added. When trivalent impurity is added to pure semiconductor, it is know as P-type semiconductor. In P-type semiconductor holes are majority carriers whereas electrons are minority carriers. Impurities such as indium, galium are added.
What is the name given to the semiconductor device that has three or more elements?
A semiconductor device with three or more elements is called a compound semiconductor. It is made up of elements from different groups on the periodic table, allowing for unique properties and applications in electronics. Examples include gallium arsenide (GaAs) and indium phosphide (InP).
What is the formula for indium bromide?
Indium forms the following bromides InBr3, indium tribromide, indium (III) bromide InBr, Indium monobromide, Indium(I) bromide InBr2, indium dibromide, In+ InBr4- , indium (I,III) bromide there are others which are not so well known

What is led and how does it work?
A light emitting diode is a special type of diode made of transparent semiconductor (silicon & germanium are opaque) like aluminum indium gallium phosphide. The selected semiconductor must also have a large enough band gap that when electrons fall into holes photons are emitted.
