Analyze the relationship among germanium, gallium arsenide, and zinc selenide. Does it make sense that GaAs and ZnSe should also be good semiconductors?

A symmetric GaAs/AlAs RTD has a barrier width of 1.5 nm and a well width of 3.39 nm. When this RTD is inserted in the base of an HBT with an emitter flux centered on the first excited level of the RTD. Find the cutoff frequency of the HBT with the inserted RTD, if the original fT was 100GHz. [Hint:The transit time across the RT structure is given by (d/vG) + (2h/Γ)where d is the width of the RT structure,...

Assume 800 nm unpolarized light is incident into a 100 micrometer GaAs wafer. How much (%) of the light will be reflected? How much will be absorbed (%)? How much will be transmitted (%)? Sketch the geometry and explain your reasoning and assumptions. You can take refractive index of GaAs at 800 nm as 3.68. αGaAs=2x104cm−1

You need to electroplate a 140-nm-thick zinc coating onto both sides of a very thin, 1.0 cm × 1.0 cm copper sheet.

You need to electroplate a 140-nm-thick zinc coating onto both sides of a very thin, 1.0 cm × 1.0 cm copper sheet. You know that the charge carriers in the ionic solution are divalent (charge 2e) zinc ions. The density of zinc is 7140 kg/m3. How many seconds will it take the zinc to reach the desired thickness?
