การวัดลักษณะสมบัติของโครงสร้างนาโน ZnO ที่เตรียมโดยกระบวนการขนถ่ายเฟสไอโดยใช้สารผสม ZnO/CNTs

โครงสร้างนาโน ZnO ได้ถูกเตรียมลงบนแผ่นฐาน Si โดยเทคนิคการขนถ่ายเฟสไอโดยใช้สารตั้งต้นเป็นสารผสม ZnO/CNTs กระบวนการนี้สามารถทำได้ที่อุณหภูมิต่ำกว่าจุดหลอมเหลวของ ZnO สัณฐานของผิวหน้า องค์ประกอบทางเคมีและโครงสร้างของผลึกได้ถูกตรวจสอบ และวัดโดยกล้องจุลทรรศน์อิเล็กตรอนแบบส่องกราด (SEM) การวิเคราะห์ธาตุเชิงพลังงาน (EDS) และการทดลองการเลี้ยวเบนของรังสีเอ็กซ์ (

From single ZnO multipods to heterostructured ZnO/ZnS, ZnO/ZnSe, ZnO/Bi2S3 and ZnO/Cu2S multipods: controlled synthesis and tunable optical and photoelectrochemical properties

CrystEngComm, 2010
This manuscript describes the selective modification of ZnO multipods with a series of wide bandgap and narrow bandgap semiconductors (ZnS, ZnSe, Bi2S3, and Cu2S). ZnO multipods are firstly synthesized via the aqueous phase reaction of Zn2+ ions with KOH at a temperature lower than 70 °C, which is simple, facile and free of organic capping agents ...

Room temperature blue LED based on p-ZnO/(CdZnO/ZnO) MQWs/ n-ZnO

Journal of Luminescence, 2016
Abstract Blue multiple quantum well light-emitting diodes comprising of p-ZnO/(Cd0.12Zn0.88O/ZnO) multiple quantum wells/n-ZnO were grown on n-Si substrates using dual ion-beam sputtering deposition technique. X-ray diffraction of individual thin films revealed growth preferentially in c-axis direction perpendicular to the substrate ...

The paper presents a short review of studies of ZnO coatings. Using a method of X-ray phase analysis (DRON-2.0 device in Cu-k emission), measurements of optical transmission, optical absorption (the Spectrophotometer ENGLAND (1000SERIES=CECIL 1021), optical density using a laser stand, and measurements of volt-ampere characteristics, it was revealed ...

We propose a procedure for synthesis of nanometer-sized thread-like zinc oxide crystals by gas epitaxis via the mechanism ???vapor-liquid-crystal??? (VLC). Arrays of statistically distributed nano-whiskers on polished silicon substrates were prepared. Samples were studied by x-ray diffraction analysis and scanning electron microscopy (SEM).
