1. THEORY: Generating & testing the basis sets. Structureoptimization. Comparing bond lengths with experiment.Creating and testing potentials for diamondoids &derivatives and pseudopotentials for metal tips. Testingdifferent density functionals (B3LYP, GGA, LSDA & LDA).Testing and comparing results from the ab initio codes (Molpro, Gaussian 03, etc.). Treating valence electronsexactly.

2. EXPERIMENTS: Preparing monolayers of diamondoids.Obtaining images with AFM and/or STM. Preparing samplesusing different solvents (THF, toluene, etc) with differentdegrees of concentration levels. Choosing substrates (Si,Mica, etc.). Choosing preparation techniques (drop,spinning, etc.). Force-distance calculations andcharacterization (through XPS, STM, and AFM). Testingversus THEORY results.

3. SIMULATIONS: Simulations to produce self-assemblies fornew materials with desired optoelectronic properties asMEMS, NEMS and other micro- and nano-gears anddevices. Utilizing the intermolecular potential data producedin the above sections.
