Nano-dots of 110 nm diameter and 37 nm height were successfully fabricated. Laser irradiated PtO x decomposed to Pt and oxygen leading to additional surface protrusion due to the combination of the thermally induced interdiffusion of the TbFeCo and ZnS-SiO 2 region and PtO x decomposition induced compressive stress. To address this problem, a PtO x film was inserted between the TbFeCo and ZnS-SiO 2 layers. Typical nano-dot height, however, was less than 20 nm and this value is not sufficient for the pit height of an optical master disk. This technique was used to fabricate nano-dots with dimensions less them 100 nm on the sample surface. Application of heat to these materials induces interdiffusion and as a result local volume expansion leading to the formation of a convex surface region. The combination of the temperature distribution induced by a focused laser spot with a Gaussian distribution and a special multilayer consisting of TbFeCo and ZnS-SiO 2 are utilized. The edges would either extend beyond what is visible on the screen, have sections of the screen that aren’t covered by the image, or a stretched image.Volume change thermal lithography has been developed as a low cost and simple lithography technique for application in optical mastering. This is important because an image that is 2:3 will not fit perfectly on a 1:2 screen. A 4 x 8 or 20 x 40 screen would both have resolutions of 1:2. What proportion is the screen’s width to height? Aspect ratio measures width to height and then reduces it, like you would a fraction. The higher the resolution, the higher the image quality and more detail included in the image. Because pixels aren’t always the same size, it is possible to have two devices with the same screen size and different resolutions. It is often formatted as width x height or pixels per inch. This is the number of pixels displayed on the screen. You would have the same number of pixels and the same image, just the pixels are a larger size. Imagine adding a grid overlay of 10 boxes by 10 boxes, creating a 10×10 grid on the new space and then transferring the image, box by box to the wall. Let’s say you have an drawing on a normal sheet of paper that you want to duplicate on a wall.

Pixels are not always the same size from device to device. If you colored in the squares on a piece of graph paper to create an image, each of those squares would be like a pixel. They are like building blocks many are needed to build an image. A pixel is a dot that can be manipulated. Similar to how TVs and monitors are measured, it is the length, in inches, of the screen from one corner to the diagonal corner. Screen sizes, resolutions, pixels, and aspect ratios for iPhones If you have found yourself struggling to comprehend some basic design concepts, these common design vocabulary explanations will help. As I have done with many topics that I had trouble wrapping my mind around, such as ADA compliance and cryptography, I wrote about it. With the announcement of the new iPhone X adding another aspect ratio to the iPhone squad, I found that I didn’t fully understand some of the design vocabulary that was being used.
