Perovskite solar cells have become strong contenders in the arena of photovoltaics due to the stunning rise in their efficiency from 3 % to over 20 % in just seven years. In this time, numerous device architectures and thin film deposition methods have bee ...
Downscaling of the minimal feature size, or the gate length has been the key for the exponential im-provement of the performance of the logic CMOS integrated circuits over the last six decades. How-ever, since about 2003, some fundamental limits in the dev ...
The mechanism for the growth of 3D ZnO nanowall networks in nest-like structure by a pulsed laser deposition (PLD) technique have been investigated for dye sensitized solar cells (DSSCs) and biosensor applications. As complex oxides shift towards large vol ...
(001)-epitaxial (Ba0.5Sr0.5)TiO3 (BST) thin films with different magnitudes of compressive strain were fabricated on SrRuO3/SrTiO3 substrates by pulsed laser deposition, and their electro-optic (EO) properties were characterized by modulation ellipsometry ...
This work considers the resulting material structural effects of laser-processing chemical vapor deposited (CVD) diamond. The utilized 532 nm wavelength laser had a pulse duration of 40 ns together with a spot diameter of ca. 40 mu m. The effect of cutting ...
The aim of this project is to deposit a thin film of aluminum nitride (AlN) or aluminum scandium nitride (AlScN) on a quartz substrate showing good piezoelectric properties for use in tuning fork oscillators. Quartz oscillators are commonly used in various ...
In the past half-century, the semiconductor industry has relied on the scaling of complementary metal-oxide-semiconductor (CMOS) transistor dimensions and on material and geometrical innovations to increase the computational density. Approaching the end of ...
Doped SrTiO3 thin films, 55 nm thick, were epitaxially grown by Pulsed Laser Deposition with niobium contents ranging from 2 to 5 mol% on SrTiO3 and LaAlO3 substrates. The different templates result in different growth defects, film growth mechanism and th ...
Titanium aluminum nitride ((Ti,Al)N) thin films are widely used as hard protective coating materials. Due to their remarkable tensile strength and elastic modulus carbon nanotubes (CNTs) are an ideal candidate as reinforcing components in such coatings. In ...
The study of texture in thin films is one of the possibilities to obtain information on the fundamental physical processes which govern the thin film growth. Near the substrate, the crystalline orientation of the coating layer will usually be influenced by ...
