Since the discovery that cleanability is not necessarily linked to smoothness or gloss of surfaces it is interesting to take a closer look at methods allowing surfaces to be structured on a micrometer and nanometer [...]
Controlling of the alignment of carbon nanotubes (CNTs) is very important for applications such as scanning probes, sensors, field emitters and nanoelectronics. Controlled growth of CNTs aligned at different angles to the substrate has been [...]
A novel methodology for the simulation of isotropic gas phase etching of a substrate is presented. In this method, individual substrate atoms are removed upon physical impingement of etchant gas molecules. The effects of different [...]
The spiral carbon nanofibers consisting of Pd metal cluster were grown by the Pd2(dba)3-catalyzed decomposition of gaseous acetylene on molecular sieves (Linde 13X) support. The microstructure and composition of the spiral carbon nanofibers were characterized [...]
Nanometer-sized patterned media has been of great interest in high density data storage application [1,2]. Different fabrication techniques have been studied with its unique physical properties of nanoscale features. Among these, ion-beam induced chemical vapor [...]
Most microelectromechanical system (MEMS) devices have been based on silicon. This is due to the technological know-how accumulated on the manipulation, machining and manufacturing of silicon. However, the silicon properties are poor, especially when compared [...]
We have developed a method for fabricating polymer microstructures based on electric field induced self assembly and pattern formation. A dielectric fluid placed in between to conductive plates experiences a force in an applied electric [...]
An interconnect delay begins to dominate total device delay time and consequently, operation rate at sub-micron (
Zeolitic (molecular sieves) or mesoporous materials are the promising candidates for nanoscopically-engineered materials due to their well-defined pore structures, thermal stabilities and tailor-made synthetic abilities. Several zeolitic materials with the shape of nanorod or nanofiber [...]
We describe a new approach to simulation of epitaxial growth with strain. An island dynamics model with a level set numerical method is used for the growth, a lattice statics model is used for the [...]
Proteins capable of self-assembly are crucial to many bio-architectures and have potential applications in nanotechnology. An example is the group of proteins used to construct crystalline surface layers (S-layers) in nearly all archaebacteria and many [...]

The fabrication of state-of-the-art semiconductor nanostructures is of great interest both for fundamental physics and device applications. Besides the traditional lithography techniques, local anodic oxidation by atomic force microscopy (AFM) is emerging because of its [...]
Nanostructures, which have characteristic dimensions that are difficult to achieve by conventional optical lithography techniques, are finding ever-increasing applications in a variety of fields. For applications incorporating nanodevices to gain widespread acceptance, high resolution, reliability [...]
The traditional electron beam lithography and more recently developed focused ion beam (FIB) milling/lithography techniques have been exploited for generating exposed nanometer-size nanochannels. An additional process step of sealing exposed nanochannels cant be avoided to [...]
Potential uses of crystalline molecular sieves as selective membranes, membrane reactors, chemical sensors, optical devices as well as in other new applications rely on the ability to grow them as films.1-12 The crystallinity of these [...]

The controlled synthesis and directed assembly of materials at the nanoscale remain two of the most difficult challenges for the realization of functional nanoscale devices. For example, while there has been a great deal of [...]
An easy way to cover large areas with nano-or microstructures is self-organization. Against intuition, we claim that structureless crystals in terms of surface features are well suitable for self organized structuring on the nano-and micrometer [...]
