Suppressing Effects of Ag Wetting Layer on Surface Conduction of Er Silicide/Si(001) nanocontacts

Chinese Physics Letters 2018年第8期35卷 74-78页

Current-voltage electrical characteristics of Er silicide/Si（001） nanocontacts are measured in situ in a scanning tunneling microscopy system. Introduced as a new technique to suppress surface leakage conduction on Si（001）,a silver wetting layer is evaporated onto the substrate surface kept at room temperature with Er Si2 nanoislands already existing. The effects of the silver layer on the current-voltage characteristics of nanocontacts are discussed.Our experimental results reveal that the silver layer at coverage of 0.4–0.7 monolayer can suppress effectively the current contribution from the surface conduction path. After the surface leakage path of nanocontacts is obstructed, the ideality factor and the Schottky barrier height are determined using the thermionic emission theory, about 2 and 0.5 eV, respectively. The approach adopted here could shed light on the intrinsic transport properties of metal-semiconductor nanocontacts.

Ag nanowires(AgNWs)have shown great application value in the field of flexible electronics due to their excellent optical and electrical properties,and the quality of its joints of AgNWs in the thin film network directly plays a key role in its performance.In order to further improve the joint quality of AgNWs under thermal excitation,the thermal welding process and atomic evolution behavior of AgNWs were investigated through a combination of in situ experimental and molecular dynamics simulations.The influence of processing time,temperature,and stress distribution due to spatial arrangement on nanojoints was systematically explored.What is more,the failure mechanisms and their atomic interface behavior of the nanojoints were also investigated.

High quality metal-quantum dot-metal structure fabricated with a highly compatible self-aligned process

引用

Journal of Semiconductors 2015年第12期36卷 42-47页

作者：付英春王晓峰马刘红周亚玲杨香王晓东杨富华 Engineering Research Center for Semiconductor Integrated Technology Institute of Semiconductors Chinese Academy of Sciences

A self-aligned process to fabricate a ＂metal-quantum dot-metal＂ structure is presented, based on an ＂electron beam lithography, thin film deposition and dry etching process＂. The sacrificial layers used can improve the lift-off process, and novel lithography layouts design can improve the mechanical strength of the fabricated nanostructures. The superiority of the self-aligned process includes low request for overlay accuracy, high compatibility with a variety of materials, and applicable to similar structure devices fabrication. Finally, a phase change memory with fully confined phase-change material node, with the length × width × height of 255 × 45 × 30 nm^3 was demonstrated.

关键词： fully confined nanocontacts self-aligned phase change random access memory
