| Abstract | Various unavoidable constraints (viz. physical, technical and financial) curtail the possibility of achieving continuous improvement in the computing capabilities through scaling down of devices using the conventional silicon technology. Molecular electronics aims to use the bottom-up approach to build nanoscale devices from basic molecular unit and promises unforeseen levels of computing per $dollar-watt-cm^{2}.$ The programmability feature of molecules is exploited to circumvent the problem of addressability. The nanocell concept is predicated on the belief that a random distribution of self-assembled molecules can be programmed to perform a specific logic function. In this paper we present a novel approach to demonstrate plausibility of the idea of “creating functionality from disorder”. The experimental results vindicate the plausibility of training a nanocell to perform a logic operation. A negative differential resistance (NDR) circuit has been designed to emulate the Λ-type I-V characteristics of the molecular switches connected between any pair of nodes in the actual nanocell. A nanocell model is then constructed taking instances of this NDR circuit. As a primary exploration of the nanocell concept the omnipotent programming was considered. The results from HSPICE simulations are then fed to the genetic algorithm(GA) solver in MATLAB to provide us with the optimized configuration(or a combination of switch states) of the NDR circuits for which the nanocell model yields the functionality of one or multiple target logic devices. Finally mortal programming is also accomplished. The GA solver is used again to provide us with the voltages which ought to be applied on each of the exterior nodes (apart from the input and output nodes) of the nanocell to yield a response resembling a NAND gate. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
