Photoluminescence properties of AlN homoepilayers with different orientations

Photoluminescence of GaN Nanowires of Different Crystallographic Orientations

We utilized time-integrated and time-resolved photoluminescence of a-axis and c-axis gallium nitride nanowires to elucidate the origin of the blue-shifted ultraviolet photoluminescence in a-axis GaN nanowires relative to c-axis GaN nanowires. We attribute this blue-shifted ultraviolet photoluminescence to emission from surface trap states as opposed to previously proposed causes such as strain ...

Three-dimensional AlN microroses and their enhanced photoluminescence properties.

Novel three-dimensional AlN microroses, for the first time, have been synthesized via direct reaction between Al and N(2) in arc plasma without any catalyst and template.

investigation of gassing behavior, electric and dielectric properties of different insulating fluids.

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...

Psychometric properties of childbearing orientations scale

Background and Purpose: Childbirth is a normal physiological process and a family event. Women in various societies with different cultural backgrounds have diverse reasons for childbearing. Understanding the reasons behind childbearing might help overcome some issues associated with early/late reproduction, or lack of desire to give birth. This study was an attempt to develop, validate, and st...
