Colloidal quantum dots (QDs) have been considered in the last years as a promising material for photodetectors due to size-tunable optical absorption spectra through quantum size effect. Another important advantage is solution processability that facilitates integration on a large variety of substrates, including silicon. This paper presents a hybrid PbS/silicon device prepared from solution-processed...
The emerging compressive sensing (CS) theory states that the sparsity of a signal can be exploited to reduce the ADC conversion rate. However, most previous CS frameworks still require dedicated analog CS encoders in front-of low-rate ADCs. Differently, this work proposes a fully-passive CS framework that directly embeds CS into a conventional SAR ADC, reducing the ADC power by 4 times. A prototype...
A general expression is worked out for the trap-to-trap transition probability per unit time, applicable to amorphous materials where charge conduction is dominated by localized states. The outcome is a closed-form expression involving temperature and local electric potential. It is suitable for inclusion into hydrodynamic or energy-balance numerical solvers to be used for simulating devices based...
