thank you ,asdfaaa.then i want to ask:
1 i want the bulk conductivity of high-resistivity Si in X-band (8-12GHz),can anybody tell me ,thank you!
I dont have those data, maybe you can consult your vendor.
2 "square " is often used, i want to know it represents which unit in general.
It is arbitray unit,
In a regular three-dimensional conductor, the resistance can be written as
R=ρ×L/A=ρ×L/Wt
where ρ is the resistivity, A is the cross-sectional area and L is the length. The cross-sectional area can be split into the width W and the sheet thickness t.
By grouping the resistivity with the thickness, the resistance can then be written as
R=(ρ/t)×(L/W)=Rs×(L/W)
Rs is then the sheet resistance. Because it is multiplied by a dimensionless quantity, the units are technically ohms. The term ohms/square is used because it gives the resistance in ohms of current passing from one side of a square region to the opposite side, regardless of the size of the square.
3 the last,"pitch" is what?
i will appreciated your help!
