In this paper, we review some recent work on amorphous materials using current “first principles” electronic structure/molecular dynamics techniques. The main theme of the paper is to emphasize new directions in the use of such ab initio methods. Some of these, being quite new, need development, but we believe have promise for solving new and important kinds of problems in the physics of glassy...

The technology of high speed optoelectronics has been rapidly developed in the past decade, and possible application of them to digital signal processing has been investigated, including the authors' effort to implement optically controlled digital integrated circuits [1],[2]. The advantage of utilizing optical technology supplementing the conventional electronic technology lies in the fact tha...

Because of increased interest in the development of integrated hybrid optoelectronic devices for use in photonic sensors and communication services, new methods for device fabrication by utilizing simple, fast and inexpensive process are highly desirable. In this regard, drying-mediated self-assembly of non-volatile solutes (polymers, nanocrystals, nanoparticles, nanorods and DNA) through irrev...

The recent challenges for improving the operation speed of nanoelectronics have motivated research on manipulating light in on-chip integrated circuits. Hybrid plasmonic waveguides with low-dimensional semiconductors, including quantum dots and quantum wells, are a promising platform for realizing sub-diffraction limited optical components. Meanwhile, two-dimensional transition metal dichalcoge...

In this paper, we present the design and characterization of a monolithically integrated tunable laser for optical coherence tomography in medicine. This laser is the first monolithic photonic integrated circuit containing quantumdot amplifiers, phase modulators, and passive components. We demonstrate electro-optical tuning capabilities over 60 nm between 1685 and 1745 nm, which is the largest ...

Since the discovery of mesostructured materials in the early 1990s a great deal of effort has been devoted to developing new structures, compositions, and functionalities. The ability to synthesize semiconducting singleor multicomponent metal-oxide mesostructured materials with controlled morphologies has been a major step towards functional materials with potential applications in sensing, cat...

Methylammonium lead iodide perovskite has attracted intensive interest for its diverse optoelectronic applications. However, most studies to date have been limited to bulk thin films that are difficult to implement for integrated device arrays because of their incompatibility with typical lithography processes. We report the first patterned growth of regular arrays of perovskite microplate crys...
