Lifetime spectroscopy and hydrogenation of chromium in n- and p- type Cz silicon

The defect parameters of isolated Cri and chromium-boron (CrB) pairs are reassessed by conducting lifetime spectroscopy on both nand p-type, Cr-doped silicon samples with different doping levels, and fitting the lifetimes with the Shockley-Read-Hall (SRH) model. The uncertainty ranges of the parameters are significantly tightened through a combined analysis of the two defects with the lifetime ...

Amorphous silicon on p-type crystalline silicon heterojunction

2014 A junction was grown by d.c. sputtering of n-type silicon on a p-type crystalline substrate. Ohmic contacts were deposited by evaporation of aluminum. The junction obeyed Schottky model both under forward and reverse bias conditions, but with higher idealization factor « n » due to its high internal resistance. The 1/C2-V relation showed the presence of localized and interface states. The ...

P-Type Silicon Nanowire Transistor Modeling

The presented model based on the quantum confinement and high electric filed effect illustrates velocity approach to the modeling of a P-type silicon nanowire transistor. It has been clarified that the intrinsic velocity of nanowire and other hetero-structure field-effect transistors (FETs) is governed by the transit time of holes (electrons). The length of the channel for ballistic channel is ...

P Spectroscopy using a Silicon-Based Needle Coil

INTRODUCTION: Silicon-based microcoils of planar (1,2), solenoid (3) and Helmholtz (4) design have been recently investigated, with the main intention of developing extremely cheap local coils for clinical MRS, which would not have to be cleaned but could simply be discarded. We have been developing a needle coil design for insertion into tissue. Needle coils have a very small field of view ort...
