How to Cleave your sample?

1. Top-post cleave Glue a post on the sample surface using conductive epoxy (example: Epotek H21D conductive epoxy, or Epotek E4110 conductive epoxy). It is recommended to use a post of similar surface area as that of the sample. Inside the LL, after reaching appropriate pressure, knock off the post using the transfer wobble stick to expose a clean sample surfece.

2. Tape cleave (mechanical exfoliation) You can also exfoliate the sample surface using tape (typically we use kaptone tape). See the figure.

Transfer sample to the sample rod in upper chamber

Now its time to transfer the sample plate(s) to the sample rod in the upper chamber (UC). Prior to transfer, the manipulator must be set to sample transfer positions in order to receive the sample plate. Let us know how to do this :

You need the following softwares to align the sample rod’s sample holder surface parallel to the sample plate:
