I think drift and diffusion are important in solid state because we need to know what makes carriers move.
Carriers drift in electric field and diffuse due to the difference in concentration gradient.

The important of drift and diffusion described as drift is the motion of a charged particle in response to an applied electric field while diffusion is a macroscopic motion due to carrier concentration differences.

drift and diffusion is a new chapter.its have some explanation moving an electron and hole.Dritf was due to electric field diffusion in concentration gradient..... that i know..

i think it is important because we can know the motion of the carrier base on electric field.

assalamualaikum.
from the lectures,drift is due to electric field and for diffusion, it is due to concentration gradient.

I think drift and diffusion is very important in s/c because the carrier is moved in energy level.

assalamualaikum..
drift and diffusion are important because it is the motion of the carriers or charged particle moving in s/c due to electric field n the differences in concentration gradient..in other words we can learn more about the motion of the carriers in s/c which have their own ability and functions..

hi....
Drift and diffusion are important in solid state because we can see the differences between this two motion of particle charge.
We can relate a drift due to the electric field while a diffusion with the concentration gradient..

from what i have learn, drift and diffusion is important to make the carriers move in semiconductor.

DRIFT current due to the electric field. holes will moves in the same direction with electric field and electron in the opposite way.

DIFFUSION due to the difference in concentration gradient. carriers moving from regions of high concentration to the low concentration.

Wassalam.

drift and diffusion are important in solid state because the carrier must flow in order have a current where the electron and hole must flow in semiconductor.there is 2 type of carrier motion which is drift and diffusion.drift is a carrier motion due to electric field while diffusion is a carrier motion due to concentration gradient....

in homogeneous s/c the existence of current happened when carriers flow and drift & diffusion are the things that makes carriers move, drift motion(due to electrical field), diffusion motion (due to concentration gradient),

Drift and diffusion are important in solid state becouse from there we can know the motion of carriers.
Drift can be described as carrier motion due to electric field and diffusion depands on concerntration gradient.

I think that drift and diffusion are important in solid state because we can see what and how carrier move.Drift is carrier motion due to electric field.Diffusion is a process of mobile particles flowing from region of high to low concentration.tq..

drift n diffusion both are important in solid state.drift n diffusion makes carrier move.drift is carrier motion due to electric field.from the carrier motion will result electrical current.
for diffusion, carriers diffuse due to the difference in concentration gradient.

in order to produced current, the carriers need to move..there are 2 ways of moving the carriers,1st by drifting the carriers and 2nd by diffusing it..the carriers will drift in the electric field whereas it'll diffuse when there is difference in the concentration gradient =P

The important things to know about drift and diffusion is how the electron and hole move in the semiconductor...Is it?

Drift and diffusion are very important in solid state because these two mechanisms shows how charge carriers move in semiconductor.Drift current due to the electric field and diffusion current due to the concentration gradient.

I think drift and diffusion are important because without it, semiconductor can't be operate.Thus no carriers move.

i think drift and diffusion are important because we need to know what makes carriers move.drift and diffusion has its own current density.conductivity.it is all related to drift and diffusion in the semiconductor.the relation in diffusion and drift makes the charge flow in the s/c.

Assalamualaikum,
sorry for the late..
well,
i think drift and diffusion are important in solid state because thats how carriers move. we need to know deeply on how does its moving since it is included in the lesson outcomes. carriers drift in electric field and diffuse due to the difference in concentration gradient.

Drift and diffusion are two basic mechanisms by which charge carries move in semiconductors.Drift current which result when the electrons and holes are in an electric field,while diffusion current arises when there is variation in concentration of carries with position.

driff we will look at electric field and diffusion look at the concentration

yes.. because we can know how was current flow in material..

diffusion & drift are important as they relate with the direction of electrics field..

their direction are determine by identify the concentration of carriers..

diffusion: carriers move from high concentration to low concentration..

drift: due to electric field,the carrier motion resulting electric current.

We need to know that the drift and diffusion is important in determine the motion of the carriers.
Diffusion depends on concentration of carrier while drift depends on electric field

drift and diffusion are important in solid state because there are the mechanisms by which current is flow.

drift current is resultant when electrons and hole are in an electric field,while diffussion current is arises when there is a variation in the concentration of carriers with position.

according to the notes it jz the movement of carrier...drift current is resultant when electrons and hole are in an electric field,while diffussion current is arises when there is a variation in the concentration of carriers with position.

Drift and diffussion is important because of the two thing we can the moving of the carrier. diffusion depend on the concentration gradient while the drift is depend on the electric field.........

on my view drift is important because, the movement of the carrier depends to drift.Futhermore the current will exist due to the carriers flow..While for diffusion is important to show the carrier motion due to concentration gradient..

Drift and diffusion are important n solid state because this movement will affect to the electron and hole movement. If there is no movement of electron, so there is no electric field and current produced

from my point of view,drift and diffusion are important in solid state since it is two basic mechanism by which charge carriers move in sc.drift are important since we need to know the results when the electrons and holes are in electric field. as for diffusion,it is important when there is a variation in concentration of carriers with position.

in solid state, we learned about the electron and hole. drift and diffusion are important to tell us how the carriers move.
