<b>Abstract</b><br/><br/>In recent years, the scientific community has put a lot of efforts into trying to artificially grow new functional materials by reducing their dimensionality from 2D to 1D or even 0D. However, it is not a simple task, which includes synthetic methods that could go in both possible top-down or bottom-up approaches.<br/>Our group, working on the bottom-up approach through on-surface synthesis has been able to develop unprecedented new 0D, 1D or 2D silicon nanoshapes[1,2]. Here, we demonstrate the on-surface synthesis of atomically precise silicon nanoribbons by utilizing the Ag(110) surface and also we have unmasked the unique 1D pentagonal silicon structures formed on it, which had been elusive for over 10 years. Further, we will see how the different single crystals substrates greatly affects the growth of silicon and the new structures that can be formed on it[3].<br/>Promising applications of new silicon nanoforms range from nanoelectronics to transistors or embedded sensors; however, one of the important challenges that we have to overcome is the isolation, through the separation of the substrates, of these interesting nanoforms.<br/><br/><b>Keywords:</b> Silicon nanoribbons, 1D-Silicon.<br/><br/><b>Reference</b><br/><br/>1-J.
