Tóm tắt

Bài báo này trình bày việc sản xuất các bộ phim indium tin oxide (ITO) trong suốt có độ dày siêu mỏng (<1 µm) dựa trên các bột nhão ITO dạng hạt bằng kỹ thuật thanh định hình, sử dụng chất binder polyvinyl pyrrolidone (PVP) làm phụ gia hữu cơ. Ảnh hưởng của thành phần bột nhão lên độ dày phim, điện trở riêng biệt cũng như độ truyền trực tiếp của các phim khô được đánh giá. Dung môi hữu cơ ethanol và các loại chất binder PVP khác nhau đã được thử nghiệm để chuẩn bị bột nhão và hiệu suất lớp. Các phim xanh ITO với điện trở riêng biệt thấp 3 Ω cm, độ truyền ánh sáng 87% và độ dày lớp chỉ 250 nm đã được sản xuất. Hơn nữa, ảnh hưởng của các quá trình gia nhiệt lên đến 400 °C đối với các tính chất điện của các phim ITO cũng được đánh giá.
