A three-dimensional (3-D) simulator is presented which uses a linear-response approach to simulate the conductance of semiconductor single-electron transistors at the solid-state level. The many-particle groundstate of the quantum dot, weakly connected to the drain and the source reservoir, is evaluated in a self-consistent manner including quantum-mechanical many-body interactions. A transfer-...

The research on single-electron devices (SEDs) [1] has already spanned a long history. It started with metal or superconductors in the late 80s [2, 3] and then expanded to semiconductors [4-6] in the 90s. Room-temperature operating silicon based devices [7-9] activated the research from the viewpoints of LSI application, and there have been many studies focusing on both device fabrication and c...

original article   one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf-magnetic field (mf) in substations, power plants, cities and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf meters. elf-mf was measured by tes-1394 mf tester (three-axis...

original article background and objectives: one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf- magnetic field (mf) in substations, power plants, cities, near high voltage power lines and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf mete...

The Graphene based single electron transistor (SET) as a coulomb blockade device need to be explored .It is a unique device for high-speed operation in a nano scale regime. A single electron transfers via the coulomb barriers, but its movement may be prevented by coulomb blockade, so its effect is investigated in this research. The conditions of coulomb blockade and its controlling factors such...

In this article, we report the studies of various device architectures of organic lightemitting devices (OLEDs) incorporating highly efficient blue-emitting and ambipolar carriertransport ter(9,9-diarylfluorene)s, and their influences on device characteristics. The device structures investigated include single-layer devices and multilayer heterostructure devices employing the terfluorene as one...

Single-electron transistor (SET) is a key element of current research area of nanotechnology which can offer low power consumption and high operating speed. Single electron transistor [SET] is a new nanoscaled switching device because single-electron transistor retains its scalability even on an atomic scale and besides this; it can control the motion of a single electron. The goal of this pape...
