Hi John! Hope BU is treating you well. I would use the thermal deposition and
raise the background pressure a bit. Try introducing some argon. Your surface
roughness will increase with pressure.

We'd like to deposit ~50nm Al layers with controlled surface
roughnesses ranging from ~5nm Rms to above 10nm Rms. I'm using a Sharon
e-beam evaporator system for the deposition but also have access to an
Edwards Thermal evaporator. The greater Rms roughness the better. Any
ideas?
