What do you call A small computer in which the central processing unit is a silicon chip?
don't talk about them skynets coming for ya
Why polysilicon is used as gate in mos technology?
Because of threshold voltage reduction of MOSFETs. Comparing with metals for the gate of MOSFETs, polysilicon has small work function difference with the substrate silicon of MOSFETs.
Why ordinary silicon diode does not emit light?
The energy band gap between the cathode and anode is too small to generate photons of higher energy than far IR.Silicon is opaque to visible light (and even IR).
What do you mean by DC forward voltage?
DC forward voltage is generally related to diodes. It means the voltage across the diode when the diode is forward biased, i.e. when the anode is more positive than the cathode. The forward voltage is the drop across the diode. The amount of drop is a function of current. For typical silicon diodes, the forward voltage drop ranges from 0.6 volts for very small currents, to 1.5 or more volts for large currents.
What is the physical meaning of electric flux?
Electric Flux is generally accepted as the amount of electric field passing through a perpendicular area. For curved surfaces, we sum up infinately small contribututions to small areas that are infinitely small and thus flat.
How is n-type and p-type formed?
When in intrinsic semiconductor (pure silicon) addition of small amount of impurity of group V elements (arsenic, antimony, phosphorous) makes N-type semiconductor. V group elements provides one extra electron to silicon atom. so this makes negative charge and majority of electrons. so its called N-type.. And in P-type when in pure silicon addition of small amount of impurity of group III elements (boron, aluminum) makes the P-type. by adding IIIrd group elements they they accepts the electrons from the silicon atom since its trivalent elements so there will be vacancy of 1 electron in silicon lattice resulting the formation of "hole". This makes semiconductor positive charged semiconductor called P-type.
What is the chemical formula for bare copper wire?
The chemical formula is Cu with small amount of CuO impurity.
What is doping in chemistry?
Addition of small amount of foreign impurity in the host crystal is known as doping. It increases the electrical conductivity.
What are transistors made from?
The vast majority of all transistors are nearly pure silicon, with small amount of carefully added impurities.A small but significant number of transistors are mostly germanium.
What happens to your computer when the amount of RAM is very small?
It becomes slow.
What is the definition of limit test for inorganic compound?
limit test is a quantitative or semiquantitative test designed to identify and control small quantities of impurity which are likely to be present in the substance.Basically limit test for inorganic compound is carried out so that the amount of inorganic impurity present in the drug or required material do not exceed its prescribed limit.
What happens a small amount of tobacco enters the virgina?
everything happen all of it
How are P and N type semiconductors formed?
FORMATION OF P-TYPE SEMI CONDUCTOR A P - type semiconductor is formed when a small amount of trivalent impurity is added to pure Germenium or silicon atom crystal. The addition of trivalent impurity produces a large no. of holes to the host crystals. To explain the formation of P - type semiconductor, let usintroduce a trivalent impurity into the lattice of a pure silicon crystal. The trivalent atom has 3 valanceelectrons and form covalent bonds with neighbouring atoms. The 4th bond is incomplete . the trivalent atom then attracts an electron from an adjacent atom there bycompleting the 4th bond and forming a hole in the adjacent atom. Since a trivalent impurity atom provides 1 hole, an enormous increase occurs in the number of holes. The impure crystals so obtained is called P - type semiconductor where P represents the positive charge on hole. Thus the majority carrier in a P - type semiconductor are holes. Freeelectrons are also present in the P - type semiconductor. These are thermally generated and since they relatively few, they are called minority carriers. The trivalent impurity atoms are called acceptors because each accepts an electron when the atom is introduced into the host crystal.FORMATION OF N TYPE SEMI CONDUCTORAn N - type semiconductor is formed when a small amount of pentavalent impurity is added to a pure Germenium or Silicon crystal. The addition of pentavalent impurity produces a large no. of free electrons in the host crystal.To explain the formation of N - type semiconductor, let us introduce a pentavalent impurity atom into the lattice of pure silicon crystal. The pentavalent atom has 5 valance electrons, but only 4 form covalent bonds with the neighbouring atoms. The 5th electron finds no place in the covalent bonding so becomes free. Since an impurity atom provides one free electron, an enormous increase occurs in the no. of free electrons. The impure semiconductor so obtained is then called as N - type semiconductor where N represents negative charge on an electron. Thus the majority carrier in N - type semiconductor are free electrons. Holes are also present in the N - type semiconductor. These are thermally generated and since they are relatively few, they are called minority carrier.The pentavalent impurity atom are called donour because each donate a free electron to the host crystal.
What happens if you put a small amount of alcohol on a scorpion?
i advise you not to....but if you do it probably wouldn't do anything
What happens when you loose a small amount of blood?
Nothing really happen intell you loose alot.
What happens to the small amount of sun's energy when it reaches the earth?
Nothing really it gets darker
What will happen if you lick led?
Nothing happens when you lick lead. You are ingesting a small tiny amount.
