Specific detectivity, or D*, for a photodetector is a figure of merit used to characterize performance, equal to the reciprocal of noise-equivalent power (NEP), normalized per square root of the sensor's area and frequency bandwidth (reciprical of its sampling rate).

Specific detectivity is given by $D^{*} = \frac{\sqrt{A f}}{N E P}$ , where $A$ is the area of the photosensitive region of the detector and $f$ is the frequency bandwidth. It is commonly expressed in Jones units ( $c m \cdot \sqrt{H z} / W$ )in honor of R. Clark Jones who originally defined it.^[1]^[2]

Given that noise-equivalent power can be expressed as a function of the responsivity $R$ (in units of $A / W$ or $V / W$ ) and the noise spectral density $S_{n}$ (in units of $A / H z^{1 / 2}$ or $V / H z^{1 / 2}$ ) as $N E P = \frac{S_{n}}{R}$ , it's common to see the specific detectivity expressed as $D^{*} = \frac{R \cdot \sqrt{A}}{S_{n}}$ .

It is often useful to express the specific detectivity in terms of relative noise levels present in the device. A common expression is given below.

$D^{*} = \frac{q λ η}{h c} {[\frac{4 k T}{R_{0} A} + 2 q^{2} η Φ_{b}]}^{- 1 / 2}$

With q as the electronic charge, $λ$ is the wavelength of interest, h is Planck's constant, c is the speed of light, k is Boltzmann's constant, T is the temperature of the detector, $R_{0} A$ is the zero-bias dynamic resistance area product (often measured experimentally, but also expressible in noise level assumptions), $η$ is the quantum efficiency of the device, and $Φ_{b}$ is the total flux of the source (often a blackbody) in photons/sec/cm².

Funding within the property market of Singapore is one of the few investment choices the place utilizing the bank's money couldn't be any simpler. The power of expats, to make a down payment, leverage the capital and consequently increase overall return on funding, is high in Singapore.

The Master Plan revealed that there might be more plots of land used for dwelling ownership and property launch in anticipation of the increase in inhabitants. Many analyst has revealed that they can discover an increase within the number of plots of land set aside for home ownership.

Property investment becomes much more attractive if the value is stable and will increase regularly over the long term.
