A novel stereo 3D LCD for passive interference filter glasses is presented. A demonstrator based on a standard 120Hz LCD was set up. Stereoscopic image separation was realized in a time‐sequential mode using a LED‐based scanning backlight with tw

For the first time it was possible to obtain a current gain increase to more than 0 dB at frequencies beyond the transit frequency fT by use of an SiGe resonance phase transistor (RPT). This was achieved by using a very thick base layer with a graded

We demonstrate a significant improvement of the color and transmission performance of a complementary interference filter system used for stereoscopic imaging. A 3D transmission of 30% for a UHP lamp projection system was achieved. The differences in

In heterojunction bipolar transistors current gain cut-off frequencies f 1 are limited by time constants of electron transport across the base and the collector space charge zone, This point of view favours the use of small widths of the base. Howeve

The conduction band edge of silicon consists of six minima located in k-space along 〈100〉 directions. Transitions of electrons between perpendicular valleys are induced by so-called f-type intervalley scattering processes. In this work we have st

The goal of this work was the optimization of brightness and colors performance of the interference filter system for 3D projection. Special emphasis was on avoiding, or at least reducing, the need for color correction, which was one of reasons for l

Artificial Sim/Sb1 superlattices (m=15, 30, 60) were grown by molecular beam epitaxy at very low temperatures (200°C). Rutherford backscattering spectroscopy revealed the superlattices to be single crystalline with χmin values of less than 0.04. X-

— Stereo projection using interference filters is an advanced wavelength multiplexing approach that specifically takes into account the nature of the human eye, which is characterized by three types of color receptors. Accordingly, the filters used

n-type modulation-doped Si/Si 0.5 Ge 0.5 strained layer multiple quantum well structures have been grown on (100)Si substrates by molecular beam epitaxy. The concept of strain symmetrization has been applied by inserting a strain-relaxed SiGe buffer
