The low frequency noise of lattice-matched InP-based HEMTs gate recess etched with CH4/H2 RIE and phosphoric-acid based wet etchants was studied at different gate and drain biases in a temperature range of 77 K to 340 K. The measurements showed a significa ...
We used a combination of internal photoemission and of near-field optical microscopy (SNOM) to study the lateral Variations in solid interface properties such as energy barriers and electron-hole recombination. Ln particular we investigated the fully forme ...
The sensitivity of RF CMOS receivers using a direct conversion or a low-IF architecture is strongly affected by flicker noise. This paper gives theoretical guidelines to predict the flicker noise in Gilbert-cell mixers. The conversion gain, the equivalent ...

We propose a simple quantum structure which exhibits resonant tunneling under one bias and simple tunneling under the opposite one, thus acting as a rectifier. The diode consists of a single laterally-indented barrier. Due to its particular conduction-band ...
The authors have demonstrated the operation of a simple optical bolometer by irradiating a constriction in a Y1Ba2Cu3O7-δ thin film with chopped laser light at λ=633 nm. The change in film resistivity was measured by lock-in detection of the AC component i ...
The weak-field dielectric properties of ordered, disordered, and lead-deficient disordered Pb(Sc0.5Ta0.5)O-3 (PST) ceramics (PST-O, PST-D, and PST-DV, respectively) were investigated under various de-bias conditions. The de-bias field influences the parael ...
This paper presents a detailed analysis of CSL (Current Steering Logic) [1] and compares its characteristics with FSCL (Folded Source Coupled Logic) [1,2,3], two logic families intended to be applied in mixed-mode CMOS circuits. These logic families genera ...
We investigated the I-V characteristics of the double barrier stair-well structure. Resonant tunneling current is achieved by application of an electric field, which increases the transmission under positive bias and decreases it under the reverse bias. Th ...
We report on the growth of barrier, reservoir and quantum well electron transfer (BRAQWET) structures using chemical beam epitaxy. The photoluminescence spectra of the structures are affected by the bias voltage. The QW emission line is extinguished at pos ...
