Laser ablation of target materials directly in a liquid phase is a versatile method allowing the generation of nanoparticle colloids of a great variety of materials. Especially, generation of hard ceramic nanoparticles by the laser ablation method yield significant advantages compared to chemical synthesis or mechanical milling and grinding techniques. The controlled local deposition of pu...$28.00

Presented at ICALEO 2009
Much exciting materials physics centered around graphene has been uncovered since the realization that self-standing graphene sheets are stable. The synthesis of graphene however is still problematic.
We present an alternative route to epitaxial graphene (EG) synthesis that promises to be scalable and possibly expanded to SiC-on-Si substrates. We use pulsed excimer laser radiatio...$28.00

This paper presents the growth of single-walled (SW) and multi-walled (MW) carbon nanotubes (CNTs) by laser-induced chemical vapor deposition (LCVD) on a transparent substrate at room temperature. For the CNT growth, multiple catalyst layers (Ni/Al/Cr or Fe/Al/Cr) are irradiated from the backside through the transparent substrate with a...$28.00

We report studies of laser methods for fabricating large-area, high-quality graphene. Common methods for graphene growth (PLD, MBE, thermal decomposition of SiC) apply energy evenly across an entire substrate, leading to simultaneous nucleation of graphene crystals in many locations and thus poor con...$28.00
