Spectral characteristics of InP photocathode with a surface grid electrode

Photocathodes for near infrared range devices based on InP/InGaAs heterostructures

“…The ultra-high vacuum installation was used to conduct the research in a vacuum, which could reach the level of 1·10 -9 Pa [11]. After heating in a vacuum chamber at a temperature of about 573 K, the net emitter atomic surface was received, that is ready for the activation with Cs and O 2 , which allows to form effective state of NEA on photocathode surface.…”

Application of new architectural and planning solutions to create an ecological city (on the example of Shanghai, China)

“…All these aspects should be taken into account at innovative development of territories under environmentally reconstruction from different points of view including the economy and the construction business [18][19][20][21][22][23][24][25][26][27]. An important factor in the development of such territories is solar energy [28][29][30][31][32][33][34][35][36][37][38][39]. This is especially true for China.…”

Модульный Импульсный Источник Питания Для Лазеров С Диодной Накачкой

“…To solve various problems associated with conducting scientific research, technical measurements, processing and obtaining new materials, transferring information, etc., a large number of models of optical quantum generators (lasers) have been developed and are being produced globally [1][2]. The most effective way to create population inversion in lasers is diode pumping, for both continuous and pulsed radiation [1][2][3][4]. In modern models of lasers, diode pumping is performed using diode arrays.…”

“…Для решения различных задач, связанных с проведением научных исследований, технических измерений, обработкой и получением новых материалов, передачей информации и т. д. во всем мире разработано и выпускается большое число моделей оптических квантовых генераторов (лазеров) [1][2]. Наиболее эффективным способом создания инверсии населенности в лазерах признана диодная накачка как для непрерывного, так и импульсного излучения [1][2][3][4]. В современных моделях лазеров диодную накачку осуществляют с помощью диодных матриц.…”
