Question

Which metals are suitable to make structures in GHz and THz applications?

Answer 1

In GHz applications, Copper(Cu) is mainly used to make structures and in THz applications Aluminium (Al) or Gold(Au) is used to make structure.  Pls mark it the brainliest

Answer 2

Answer:

It is because of the resistivity of the material. It has two units, ohm-m and seconds. The seconds unit tells us the amount of time the electrical signal takes to reach the other point. Basically, if I apply an electric field on Cu, you may be knowing that inside a conductor, no electric field is present, but that only happens after the electrons displace to create an equal and opposite electric field thereby making the net field inside zero. This time is in orders of 10−18 seconds and for GHz range, a feedback cycle of maximum 10−9 can be established, thus the GHz range for Cu. The resistivity in seconds of Au is also in 10−18 but, with a higher magnitude, around 9×10−18 s.
