Rolling Contact Fatigue in Ultra High Vacuum

Improved Contacts to MoS2 Transistors by Ultra-High Vacuum Metal Deposition.

The scaling of transistors to sub-10 nm dimensions is strongly limited by their contact resistance (RC). Here we present a systematic study of scaling MoS2 devices and contacts with varying electrode metals and controlled deposition conditions, over a wide range of temperatures (80 to 500 K), carrier densities (10(12) to 10(13) cm(-2)), and contact dimensions (20 to 500 nm). We uncover that Au ...

High-vacuum versus ‘‘environmental’’ electron beam deposition

Electron beam deposition ~EBD! provides an inexpensive way to fabricate nanostructures of various materials in a scanning electron microscope ~SEM!. However, the purity of metals deposited from an organometallic precursor gas is impaired by simultaneously deposited carbon coming both from the organometallic molecule and the residual contamination gas in the SEM chamber. We discuss carbon-contam...

Cu-TBPP and PTCDA molecules on insulating surfaces studied by ultra-high-vacuum non-contact AFM

The adsorption of two kinds of porphyrin (Cu-TBPP) and perylene (PTCDA) derived organic molecules deposited on KBr and Al2O3 surfaces has been studied by non-contact force microscopy in ultra-high vacuum, our goal being the assembly of ordered molecular arrangements on insulating surfaces at room temperature. On a Cu(100) surface, well ordered islands of Cu-TBPP molecules were successfully imag...
