Abstract
The neodymium (Nd) doped indium-zinc-oxide (NIZO) is a material with high mobility and great potential in transparent electronic devices. NIZO thin films were prepared by pulsed laser deposition (PLD) at 250, 350, 450, and 550 mJ/pulse laser energy, respectively. With the increase of laser energy, the films gradually change from an amorphous to an amorphous/crystalline state and the In2O3 crystals have preferential growth in the (123) plane. The average transmittance of the film is higher than 80% in the visible range. When the laser energy is 250 mJ, the carrier mobility has the highest value of 14.43 cm2 V−1 s−1, and it decreases with the increase of laser energy. The possible reason for this phenomenon is given by electronic structure and crystallization. Based on the content of defect states and the emitted particle number, the carrier concentration of the films is analyzed.
期刊介绍:
Micro and Nanostructures is a journal disseminating the science and technology of micro-structures and nano-structures in materials and their devices, including individual and collective use of semiconductors, metals and insulators for the exploitation of their unique properties. The journal hosts papers dealing with fundamental and applied experimental research as well as theoretical studies. Fields of interest, including emerging ones, cover:
• Novel micro and nanostructures
• Nanomaterials (nanowires, nanodots, 2D materials ) and devices
• Synthetic heterostructures
• Plasmonics
• Micro and nano-defects in materials (semiconductor, metal and insulators)
• Surfaces and interfaces of thin films
In addition to Research Papers, the journal aims at publishing Topical Reviews providing insights into rapidly evolving or more mature fields. Written by leading researchers in their respective fields, those articles are commissioned by the Editorial Board.
