Hybrid Mole Computer Using Vapor Phase Assembly
Abstract
The UHV vapor phase assembly of molecules was performed in a stainless steel chamber that is part of a molecular beam epitaxy (MBE) system (shown on the following page) that Professor John Bean brought to the University of Virginia from Bell Labs. This MBE system has two chambers: one that was used for silicon and germanium growth, and the second (referred to as Dep 2 from now on) we engineered for the vapor phase deposition of organic molecules. Figure 1.1: The Molecular Bean epitaxy chambers at the University of Virginia, Dep 2 15 the left chamber and Dep 1 is the right chamber. This entire section is dedicated to describing the changes that had to be made to Dep 2 in order to use it for the vapor phase deposition of organic molecules. The changes to the chamber included adding: a turbo molecular pump that would not get clogged with molecules, heaters to keep the gauges from becoming contaminated with molecules, a source for the vaporization of the liquid alkanethiols, and a special low temperature thermal cell to vaporize the powder oligo(phenylene ethynylene) (OPE) and diazo molecules. Additionally, to purify both the liquid and powder molecules prior to vaporization, we built two different purification stations that are also described in this section.
