A eletrostática e os circuitos de corrente constante são tradicionalmente discutidos sem que sua conexão seja claramente evidenciada. A estrutura conceitual e os métodos operacionais analíticos desenvolvidos no estudo da eletrostática não são

We present the concept of a leaky electronic state in the continuum in a semiconductor superlattice with a structural defect. The required conditions for such unusual electronic state were investigated through self- consistent simulations. The number

In this work we present an InGaAs/InAlAs heterostructure lattice matched with InP that holds two leaky electronic states in the continuum. An optical analogy with Bragg mirrors is used to explain the origin and the desired characteristics of the leak

We present e-mulate, an user-friendly software developed to calculate the electronic states of quantum well heterostructures. e-mulate was designed with a graphical user interface for users without previous coding skills. The unidimensional Schroding

Raw milk quality is a key component in dairy chains and it demands producers to evaluate it routinely to ensure the safety and composition of their products. The amounts of protein and fat in milk are normally used as quality standards. The protein c

In this paper, we show a superlattice quantum well infrared photodetector (S-QWIP) grown by metal-organic vapor phase epitaxy with two narrow photocurrent peaks in the mid infrared range due to transitions between the ground state from a quantum well

We have investigated the influence of the position of the dopants and the number of Bragg mirrors in the confinement of localized states in the continuum of a InGaAs/InAlAs superlattice with a structural defect. The potential profile of the conductio

We have developed a new dual color infrared photodetector based on an asymmetric multiple quantum well superlattice. Theoretical simulations on the asymmetric superlattices show that two different absorption energies will contribute to the current in

We present a study of the use of evolutionary computation in the design of a new superlattice infrared photodetector (SLIP). Four optimization algorithms were used to find the parameters of the superlattice, specifically the thickness of the quantum
