Background

The electronics industry today is based on

semiconductors due to our well-developed

ability to affect the electronic properties of the

solid

Understanding semiconductors allows us to

understand the functioning of circuit elements

as well as grasp future possibilities and

limitations

Conductors Insulators and

Semiconductors

Conductor is Solids with ldquofree electronsrdquo that is electrons not

directly involved in the inter-atomic bonding- are the familiar metals

(Cu Al Fe Au etc)

Solids with no free electrons are the familiar insulators (glass

quartz crystals ceramics etc)

Silicon is an insulator but at higher temperatures some of the

bonding electrons can get free and make it a little conducting ndash

hence the term ldquosemiconductorrdquo

Pure silicon is a poor conductor (and a poor insulator) It has 4

valence electrons all of which are needed to bond with nearest

neighbors No free electrons

1 Teori Semikonduktor (Semiconductor Theory)

Semiconductor material are in between conductors

(like metals) and insulators (like glass)

1048766 In pure form it is non-conducting

1048766 Eg silicon crystal - has 4 electrons in its outer

orbital which form perfect covalent bonds with four

neighboring atoms leaving no electrons to conduct

electric current

1048766 The behavior of silicon can be change and turn it

into a conductor by doping it In doping you mix a

small amount of an impurity into the silicon crystal

Generally there are two types of semiconductor

Intrinsic

Extrinsic

a Intrinsic semiconductor

Intrinsic semiconductor made form pure

semiconductor like silicon or germanium

T = 0 K

In low temperature 0 K all of

valence electrons are

bounded No free electron

Pada temperatur kamar banyak

elektron valensi yang terlepas

dari ikatan kovalen (free

electron) karena tereksitasi

termal Bila diberi medan listrik

maka elektron akan bergerak

menjadi aliran atau arus listrik

Saat atom terionkan maka pada atom akan timbul lubang

(hole) elektron yang bebas dari ikatan kovalen disebut

Elektron intrinsik Sedangkan lubang yany terjadi oleh

terbebasnya elektron intrinsik disebut lubang intrinsik

Semiconductor Doping

N-type In N-type doping phosphorus or arsenic is added to

the silicon in small quantities

Phosphorus and arsenic each have 5 outer electrons

The 5th electron has nothing to bond to so its free to

move around

The created free electrons allow an electric current to

flow through the silicon

Electrons have a negative charge hence the name

Ntype

P-type

1048766 I n P-type doping boron or gallium is the dopant

1048766 Boron and gallium each have only three outer

electrons

1048766 When mixed with silicon they form holes in the

where a silicon electron has nothing to bond to

1048766 The absence of an electron creates the effect of a

positive charge hence the name P-type

1048766 Holes can conduct current A hole happily accepts

an electron from a neighbor moving the hole over a

space
