摘要:
Here we describe the design, construction, and operation of an ultrahigh‐vacuum manipulator for combined molecular beam and scanning tunneling microscopy experiments. The manipulator allows (1) sample transfer, (2) liquid‐nitrogen cooling, (3) electron beam heating, (4) rotation about the vertical and horizontal axes, and (5) electrical isolation of the sample. The unique features of the design are (a) direct transfer of a 3/8‐in.‐diam sample to a load‐lock sample carrier without the use of a second transfer arm and (b) sample mounting and electron beam heating systems that permit the sample to be several hundred degrees hotter than the sample mounting plate, thus minimizing sample contamination.
