Novel quantum wire infrared photodetectors

Infrared Radiation Photodetectors

“…To eliminate the limitations of QWIP detectors, there has been significant interest in IR detectors with lower dimensions such as quantum wires (QR) (2-D) and quantum dots (QD) (3-D) (Das & Singaraju, 2005). The use of quantum wires and quantum dots for IR detection provides many advantages.…”

Fabrication and Applications of Metal Nanowire Arrays Electrodeposited in Ordered Porous Templates

“…'templates', for a myriad of 1D and composite nanomaterials in the name of fundamental and/or technological interests [Martin, (1994); Wade & Wegrowe, (2005)]. The template synthetic method is so versatile [Hurst et al, 2006;Das, B. & Singaraju, P. (2005); Liang et al, (2002)] that its applications are as vast as the imagination!…”

Characteristics analysis of quantum wire infrared photodetectors under both dark and illumination conditions

“…By substituting from Eqs. (11), (12) into Eq. (15), one gets the general formula for the dark current ratio between QR and QW as follow;…”

“…To address these limitations, there has been significant interest in IR detectors with lower dimensions such as quantum wires (1D) [8,9] and quantum dots (0D) [10]. The use of quantum wires and quantum dots for IR detection provides many advantages as summarized below [11,12]:…”
