Question

nanotechnology subject

I need a full presentation that covers

1- semiconductor materials introduction

2-semiconductor materials methods

3-semiconductor materials applications

with figures and illustrations

and the presentation needs to be in details and with refrences

the presentation should be atleast 15-20 slides

Answer 1

Sobition'. - gntroduction gntroduction of Semiconductor materials. * Semiconductors are Gan materials act as that good - essentially conductors, be Conditioned a or to good insulators or any thing in between * Commen elements such as Carbon, silicon, and ger- manium are semiconductors. * Silicon is the best and most widely used as Semiconductor material. * There are two types commonly known as P-type semiconductor & N-type semicond * # The Pilicon doped with extra electrons i called an N type semiconductors. (N us stands for Negative) Silicon Joped with material miering electrons that produce locations called holes is p-type semiconduc- too (P- stands for positive ) Semiconductor Materials Method

CD si or germanicom i Covcelent bondo Bonding Electrom. * - The nature of added impurity determine the nature of semiconductor either n-type of p-type. * come from group IV Elements beriodic semiconductor table. Semiconductor Materials application: - * Gt us wed as inqulator at low temperature: * 9+ is used a conductor at high temperature. + 9+ us used in rectifiers which are in dic. power supplies. * wave shaping cpt such as clipping and clamping. * portable radios and tou. receivers.
