Wafer from Cambridge. Received on 15/01/2020

This is an induced wafer.

Growth details

Here is a scan of the MBE growth sheet:

Essentially the growth is:W1558_growth_sheet.pdf

Al - 10 nm
GaAs - 2nm
AlGaAs - 33nm
GaAs -


Characterisation details

Here are characterisation data from the MBE growers (if available) - (insert scanned jpg here).

Here are some of our own characterisation data (insert jpg & details of measurement T, date, by whom, file location)

Material usage

Here is a scanned copy of the wafer usage sheet from the measurement lab.

This should be updated regularly by whoever takes a piece of wafer.

Processing hints / tips

Please give details of processing that worked well for this wafer. Even a scan of a lab-book page, with details of contact resistances etc.
