Integrated Photodetectors Based on Group IV and Colloidal Semiconductors: Current State of Affairs

Abstract: With the aim to take advantage from the existing technologies in microelectronics, photodetectors should be realized with materials compatible with them ensuring, at the same time, good performance. Although great efforts are made to search for new materials that can enhance performance, photodetector (PD) based on them results often expensive and difficult to integrate with standard technologies for microelectronics. For this reason, the group IV semiconductors, which are currently the main materials for elec… Show more

“…Saturation current (I o ) is the intercept of the semilog plot of Equation (6). Minimization of I o is essential to enhance performance of photodetectors, [106,107] especially in solar cells, due to its inverse dependence on V oc as seen in Equation (9). Graphically, I o can be estimated from I-V plots, as shown in Figure 13b.…”

“…Commercialized PbS infrared detectors are of the photoconduction type, where external bias is applied to the devices [ 17 , 18 ]. Due to the narrow bandgap (~0.4 eV), the dark current background noise is expected to be relatively large, reducing the detectivity.…”

“…During the past few years, research on electronic photonic integrated circuit (EPIC) increased tremendously due to its potential features like low cost, high speed data processing etc [1,2]. In this regard many works have been reported which endeavour and implemented major parts of EPIC like detector, interconnects [3][4][5]. However, the quest of all group-IV optical sources is still not fulfilled which actually make the backbone of EPIC.…”
