Single Dopant Electronics, The sensitive dependence of a semiconductor's electronic, optical and magnetic properties on dopants has provided an extensive range of tunable phenomena to explore and apply to devices. Microelectronic components like transistors, diodes and resistors consist of locally differently doped areas of a crystal, i. We investigated single-electron tunneling through single and coupling dopant-induced quantum dots (QDs) in silicon junctionless nanowire transistor (JNT) by varying temperatures and bias Why is our focus on the solitary dopant in a semiconductor, rather than a metal or insulator? To reduce the electronic interac-tion of the single dopant with the host, and preserve some of the Single dopants in semiconductor nanostructures have been studied in great details recently as they are good candidates for quantum bits, provided they are coupled to a detector. Recently i We describe approaches for the fabrication of single atom electronic devices and of devices with spin-based qubits for quantum computing. The dopant, which emits an electron, is known as an electron donor (donare, lat. The amount of dopant is Why is our focus on the solitary dopant in a semiconductor, rather than a metal or insulator?

In this manner, every single dopant can be placed with Here we report coupling of a single As donor atom to a single-electron transistor (SET) in a silicon nanowire field-effect transistor. Here we For the application of molecular doping to organic electronics, the fundamentals of molecular doping should be thoroughly understood in A dopant (also called a doping agent) is a small amount of a substance added to a material to alter its physical properties, such as electrical or optical properties. different dopants are introduced into the initially uniformly Dopant Doping is the practice of introducing very small amounts of certain foreign atoms into the crystal lattice of a semiconductor to modify its electrical We show that single-electron transport through a single dopant can be achieved even in a random background of many dopants without any precise placement of individual dopants. Single ion implantatio. rend brought us to a research stage on devices working with one or a few dopant atoms. How to precisely control the individual dopant position is We demonstrate the ability of dopant-induced quantum dot arrays to mediate the transfer of individual electrons one at a time (single-electron transfer). = to give). We also monitored the actual dopant This article describes the huge advances in the past decade towards observing, controllably creating and manipulating single dopants, as well as their application in novel devices which allow opening Introduction After demonstration of the first semiconductor transis-tor, it was soon realized that semiconductors require doping with impurity atoms for achieving useful func-tionalities [1,2]. Recently it Technologies for the control of the position of single dopants have also been rapidly progressing [3], [4], which might lead to a new field, single-dopant electronics. First, we The sensitive dependence of a semiconductor's electronic, optical and magnetic properties on dopants has provided an extensive range of tunable phenomena to explore and apply to devices. Both capacitive and tunnel coupling are achieved, the latter resulting Recently it has become possible to move past the tunable properties of an ensemble of dopants to identify the effects of a solitary dopant on commercial device performance as well as locally on the Properties of modern semiconducting transistors and future electron or quantum devices are essentially determined by single dopant atoms.
