Present status of amorphous In–Ga–Zn–O thin-film transistors

Kelvin probe force microscopy and its application

Detection of individual molecular adsorption, which represents the ultimate resolution of gas sensing, has rarely been realized with solid-state devices. So far, only a few studies have reported detection of individual adsorption by measuring the variation of electronic transport stemming from the charge transfer of adsorbate. We report room-temperature detection of the individual physisorption of carbon dioxide molecules with suspended bilayer graphene (BLG) based on a different mechanism. An electric field introduced by applying back-gate voltage is used to effectively enhance the adsorption rate. A unique device architecture is designed to induce tensile strain in the BLG to prevent its mechanical deflection onto the substrate by electrostatic force. Despite the negligible charge transfer from a single physisorbed molecule, it strongly affects the electronic transport in suspended BLG by inducing charged impurity, which can shut down part of the conduction of the BLG with Coulomb impurity scattering. Accordingly, we can detect each individual physisorption as a step-like resistance change with a quantized value in the BLG. We use density functional theory simulation to theoretically estimate the possible resistance response caused by Coulomb scattering of one adsorbed CO2 molecule, which is in agreement with our measurement.

Room temperature detection of individual molecular physisorption using suspended bilayer graphene.

A memory device includes a memory node (1) to which charge is written through a tunnel barrier configuration (2) from a control electrode (9). The stored charge effects the conductivity of a source/drain path (4) and data is read by monitoring the conductivity of the path. The charge barrier configuration comprises a multiple tunnel barrier configuration, which may comprise alternating layers (16) of polysilicon of 3 nm thickness and layers (15) of Si3 N4 of 1 nm thickness, overlying polycrystalline layer of silicon (1) which forms the memory node. Alternative barrier configurations (2) are described, including a Schottky barrier configuration, and conductive nanometre scale conductive islands (30, 36, 44), which act as the memory node, distributed in an electrically insulating matrix.

Memory device with improved charge storage barrier structure

This book gives a comprehensive description of the physics and applications of resonant tunnelling diodes. The opening chapters of the book set out the basic principles of coherent tunnelling theory. The effects of impurity scattering, femtosecond dynamics, non-equilibrium distribution and intrinsic bistabilities are then described in detail. The applications of RTDs, such as in high-frequency signal generation and multi-valued data storage, are also reviewed. The book closes with a chapter devoted to the more recent field of resonant tunnelling through laterally confined zero-dimensional structures. Covering all the key theoretical and experimental aspects of this stimulating area of research, the book will be of great value to graduate students of quantum transport physics and device engineering, as well as to researchers in both these fields.
