  • Material Solutions for Consumer Electronics

    Dr. K. P. Surendran,   

    Consumer electronics comprises of electronic equipments intended for everyday use, most often in entertainment, communications and office productivity. By definition, a product containing an integrated circuit or IC - a small electronic device made out of a semiconductor material, is called an electronic product. At the heart of an integrated circuit, there is microprocessor which is a semiconductor chip which can be programmed to do various functions. According to Moore\'s Law, for a given price, the semiconductor functionality doubles every two years. Due to the ever-growing demands for light weight, faster and compact consumer devices, the silicon chip is undergoing tremendous pressure for further miniaturization. These demands at the integrated chip level, pose uphill tasks before a material scientist like say, develop a chip interconnect more efficient than copper, develop an inter-dielectric with as low K as possible, and develop a gate dielectric better than silica. On top of this, we will reach a point where the very existence of silicon itself is at stake due to the internal heat and leakage current at atomic level. The storage capacity of the memory devices are also tremendously expanding. Hence more energy efficient devices based on spintronics and magnetoelectric phenomena are actively pursued. Developing such a multiferroic memory is expected to reduce the memory cell size to less than 20 nm while maintaining a capacity of 1Tb/(inch)2

  • Micro- and nano-structured surfaces using self-assembly and colloidal lithography

    Dr. Saju Pillai,   

    Today, fabricating micro- and nanostructured surfaces is an ingenious combination of bottom-up chemistry and top-down engineering. Currently, several fascinating bottom-up approaches employed for fabricating and manipulating micro- and nano-scale patterns on various surfaces. Among that self-assembly and colloidal lithography paved great attention to the scientific world. In this presentation, I will discuss some of the major developments occurred in the field of colloidal self-assembly and colloidal lithography.

  • Ceramic Glaze :- Role of Advanced Functional Materials

    Dr. Anantha Kumar,   

    Traditional white-ware, sanitary ware bodies and building ceramics tiles invariably require mechanically stable, impervious, water/moisture repelling glassy top-coats, conventionally named as \'glaze\'. Ceramic tiles sectors have made significant technological advancements in the manufacturing of tile bodies largely in synthetic raw materials, sintering, and product reliability. Other factors such as controlling the physical dimensions and aesthetic appearance are also given due importance. Unfortunately the Glazing technique and technologies have not been given much attention. The recent developments in Nano-Science and Technology has grown in multiple directions in the field of making functional materials. This talk covers an over view of the role of nano particles in the area of advanced multifunctional glaze for developing new kinds of products. For example, the self-cleaning concept in ceramic tiles is spreading and huge numbers of patents are filed by various companies. Similarly, glaze with special functionalities are definitely important and it is one of fields for the Nano-Markets. Analyzing the various research publications and patents for functional glaze is mainly discussed in this colloquium.
