We study the guided self-assembly of symmetric/asymmetric diblock copolymer (BCP) films on heterogeneous substrates with chemically patterned surface by using a coarse-grained phase-separation model. During the procedure, the free energy employed for the BCP films was modeled by the Ginzburg-Landau free energy with nonlocal interaction, and the flat, chemically patterned surface was considered ...

The malleable nature of atomically thin graphene makes it a potential candidate material for nanoscale origami, a promising bottom-up nanomanufacturing approach to fabricating nanobuilding blocks of desirable shapes. The success of graphene origami hinges upon precise and facile control of graphene morphology, which still remains as a significant challenge. Inspired by recent progresses on func...

In-line metrologies currently used in the semiconductor industry are being challenged by the aggressive pace of device scaling and the adoption of novel device architectures. Metrology and process control of three-dimensional (3-D) high-aspect-ratio (HAR) features are becoming increasingly important and also challenging. In this paper we present a feasibility study of through-focus scanning opt...

The International Technology Roadmap for Semiconductors (ITRS) identifies emerging technologies with the potential to sustain Moore’s Law. A necessary succession from planar CMOS to non-planar/dual-gate CMOS, and ultimately to novel architectures such as carbon nanotube(CNT)-based nanoelectromechanical systems (NEMS) is envisioned. The ITRS also identifies critical roadblocks currently precludi...

Green nanotechnology with the goal of producing sustainable nanomaterials in an eco-friendly approach is becoming an increasing necessity for nanomanufacturing industries. In this regards, biosynthesis is well adopted as a viable method for producing benign nanoparticles for biomedical application. The present study aimed at optimization and study of the effects of external stimuli pH and gold ...

Near-field radiative heat transfer (NFRHT) between irregularly shaped dielectric particles made of ${\mathrm{SiO}}_{2}$ and morphology characterized by Gaussian random spheres is studied. Particles are modeled using the discrete system Green's function (DSGF) approach, which a volume integral numerical method based on fluctuational electrodynamics. This applicable to finite, three-dimensional o...

Introduction and Background: Ceramics are inorganic, nonmetallic materials, such as alumina, beryllia, or glassceramic, whose final characteristics are produced by subjection to high temperatures. Nanomaterials is a rapidly growing area of ceramics [1-3] and can be classified into the following categories: Nano-particles submicron or ultra micron size particles; Nano-fibers – nanometer (nm) siz...

The commercialization of electronic devices requires the high efficiency and stable mirconanomanufacturing processes that allow frequent design upgrades. R2R Nano is a gateway to science and engineering research that aims to impact the widespread adoption of R2R technologies for low-cost, high-volume production of high technology products on flexible substrates. However, there are lots of the m...
