Characterization of Conduction Mechanism in Cu Schottky Contacts to p-type Ge

Spin Absorption Effect at Ferromagnet/Ge Schottky-Tunnel Contacts

We study the influence of the junction size in ferromagnet (FM)/semiconductor (SC) contacts on four-terminal nonlocal spin signals in SC-based lateral spin-valve (LSV) structures. When we use FM/Ge Schottky-tunnel junctions with relatively low resistance-area products, the magnitude of the nonlocal spin signal depends clearly on the junction size, indicating the presence of the spin absorption ...

Electrical Properties and Interface States of Rare-Earth Metal Ytterbium Schottky Contacts to p-Type InP

The electronic parameters and interface state properties of Yb/p-InP Schottky diode have been investigated by current­voltage (I­V), capacitance­voltage­frequency (C­V­f ) and conductance­voltage­frequency (G­V­f ) measurements at room temperature. The barrier height and ideality factor of the Yb/p-InP Schottky diode are found to be 0.68 eV (I­V)/0.79 eV (C­V) and 1.24, respectively. As well, t...

Low Resistance Ohmic Contacts to p-Ge C on Si

We report on ohmic contact measurements of Al, Au, and W metallizations to p-type epitaxial Ge0:9983C0:0017 grown on a (100) Si substrate by molecular beam epitaxy (MBE). Contacts were annealed at various temperatures, and values of specific contact resistance have been achieved which range from 10 5 cm2 to as low as 5:6 10 6 cm2. Theoretical calculations of the contact resistance of metals on ...

Effect of Inductively Coupled Plasma Etching in p-Type GaN Schottky Contacts

Conduction coefficient modeling in bilayer graphene based on schottky transistors

Nowadays carbon nanoparticles are applied on the island of single electron transistor and Nano-transistors. The basis of single electron devices (SEDs) is controllable single electron transfer between small conducting islands. Based on the important points in quantum mechanics, when a wave passes through several spatial regions with different boundaries, the wave function of the first region di...
