where a B = ɛℏ 2 /m ∗ e 2 is the effective Bohr radius (in Gaussian units), ɛ is the dielectric constant of the semiconductor, m ∗ is the effective electron mass, ℏ is the Planck ...

Porcelain has a dielectric constant of around 6.9, while the HDPE has a dielectric constant of 2.3. This essentially sets up a voltage divider circuit between the conductor itself and the ground ...

Porcelain insulators have proven to be unsuitable for insulated conductor applications, simply because the difference in dielectric constants between porcelain and polyethylene will eventually lead to ...

In semiconductors, the dielectric constant plays an important role by providing effective “screening,” or protection, of the conducting electrons from other charged defects in the material.

In semiconductors, the dielectric constant plays an important role by providing effective "screening," or protection, of the conducting electrons from other charged defects in the material.

Gate insulators remain a cornerstone in the evolution of semiconductor devices, playing a critical role in regulating the flow of current while minimising leakage and improving the performance and ...

Sep 30, 2021: New strategy achieves electric insulator polyethylene with high thermal conductivity and dielectric strength (Nanowerk Spotlight) Polymers are ideal for energy storage for transportation ...

Hafnium oxide is an electrical insulator which is used in optical coatings, capacitors and transistors, among other applications. Many companies are currently using hafnium oxide to replace silicon ...

Once considered merely insulating, a change in the angle between silicon and oxygen atoms opens a pathway for electrical charge to flow. A breakthrough discovery from the University of Michigan has ...

A semiconductor is a material product with some of the properties of both insulators and conductors (hence semi, meaning half or partial, conductor). Semiconductors are usually comprised of ...

While hafnium oxide (HfO 2) and zirconium oxide (ZrO 2) are well-known high-k materials, recent research has expanded the list to include tantalum oxide (Ta 2 O 5), aluminum oxide (Al 2 O 3), and ...
