Electromagnetic metamaterials with negative physical parameters such as negative dielectric constant and negative magnetic permeability have attracted widespread attention in the academic ...

The lower this constant is the smoother terahertz waves can pass through a material. Unfortunately, silicon which is a key material in chips and electronic circuits has a high dielectric constant.

Silicon transistors already have confronted this issue, which led to the introduction of high-k gate dielectric materials. As the dielectric constant (k) increases, the same capacitance is achieved ...

Heterostructures, Porous Silicon, Photonic Bandgap, Dielectric Multilayers. Introduction Porous silicon has attracted attention due to its efficient visible photoluminescence [1], the capability to ...

Darker Silicon MRAMs offer “less volatile” cache to address dark silicon dilemma. Submit. Subscribe. Home; Systems & Design; ... Advances such as the introduction of high dielectric constant gate ...

Because the dielectric constant of silicon is much higher than that of air, most terahertz waves are reflected at the silicon-air boundary rather than being cleanly transmitted out the back. Since ...

Automated ab initio calculations have been used to screen 1,800 oxides to find those with both a high dielectric constant ... Maria, J.-P. & Streiffer, S. K. Alternative dielectrics to silicon ...
