Irish scientists have made breakthroughs in the field of structural analysis of nanomaterials

At the end of July 2017, science published a study led by the university of trinity in Ireland: the nano-copper membrane could not be flat.It is pointed out that the crystal particles that make up the copper surface are unlikely to fit perfectly, and there are oblique and angular changes in each other, causing dislocation and surface roughness.Researchers from the UK, us scientists and Intel corporation were also involved in the study.
 
The electron, temperature, and mechanical properties of the material are generally determined by the composition of the grains.In the past, these grains were thought to fit together like blocks, and there would be gaps between them.Irish researchers focus on the integrated circuit nanoscale metal copper, widely used in scanning tunneling microscopy (STM) was used to measure the three dimensional structure, including the Angle between adjacent grain, intergranular is found with rotation Angle.As a result, the surface of the nano membrane cannot be absolutely smooth.
 
The study will have an unprecedented impact on the design of nanoscale materials.The task group found a way to control the properties of the material by controlling the rotation of the grain.For example, the battery life of mobile terminals such as mobile phones can be prolonged by designing to reduce resistance.In addition to consumer electronics, the study has implications for medical implants and diagnostics.
