We report homoepitaxial growth of large sized lightly boron doped CVD diamond on HPHT diamond (100) substrates. Light boron doping was achieved by using a solid boron nitride disk as a substrate holder. Colourless boron doped diamonds with no macrosc

With the increasing use of lead-free solder alloys in modern electronics, low melting materials are often required to protect the heat-sensitive parts during soldering operation. Alloy systems based on Sn/Cu/Ag offer more reliable solutions and addre

An electrocaloric (EC) effect is the temperature change accompanied by the change in electric field intensity of a thermally isolated system. The EC effect is relatively new and a challenging research topic in the field of ferroelectric materials. In
