Nanoscale heat flow plays a crucial role in many modern electronic and optoelectronic applications, such as thermal management, photodetection, thermoelectrics and data communication. Two-dimensional layered materials are beginning to confirm their groundbreaking role in many of these applications. Perhaps even more promising are so-called van der Waals heterostructures, consisting of different layered two-dimensional materials stacked…
Flexible Transparent Conductor is Free of Reflection
Transparent conductors are one of the key elements of today’s electronic and optoelectronic devices such as displays, light emitting diodes, photovoltaic cells, smart phones, etc. Most of the current technology is based on the use of the semiconductor Indium Tin Oxide (ITO) as a transparent conducting material. However, even though ITO presents several exceptional properties,…
