A Novel Position-Sensitive Linear Winding Silicon Drift Detector

open access: yesMicromachines
A novel position-sensitive linear winding silicon drift detector (LWSDD) was designed and simulated. On the frontside (anode side), the collecting anodes were set on both sides of the detector, and an S-shaped linear winding cathode strip was arranged in

Conjugate two-dimensional electric potential maps

open access: yes, 2018
Two dimensional electric potential maps based on voltage detection in conducting paper are common practice in many physics courses in college. Most frequently, students work on `capacitor-like' geometries with current flowing between two opposite ...

The dynamic electric polarizability of a particle bound by a double delta potential [PDF]

open access: yes, 2008
In this paper we derive an expression for the dynamic electric polarizability of a particle bound by a double delta potential for frequencies below and above the absolute value of the particle's ground state energy. The derived expression will be used to

Semimetalic graphene in a modulated electric potential

open access: yes, 2008
The $\pi$-electronic structure of graphene in the presence of a modulated electric potential is investigated by the tight-binding model. The low-energy electronic properties are strongly affected by the period and field strength.

Solution for the electric potential distribution produced by sphere-plane electrodes using the method of images

open access: yesRevista Brasileira de Ensino de Física
The solution for the potential distribution between a spherical and planar electrode is briefly reviewed and derived in a simple way using the method of images. An analysis of the convergence of the potential, as a function of the number of image charges
