Analysis of spectroscopy on thin films, bulk and gas samples with app.speqqle

Materials & Samples

Is your sample a semiconductor wafer, a coated material, a layered stack of paint or complex materials or even a gas?


With app.speqqle you can analyse all your data in one place! It supports bulk, multilayer or gas samples. Each component of your sample (layer or gas component) is described by a material model that describes its optical response.

Analysis of Reflectivity, transmission, reflection, absorbance, ellipsometry, THz, Terahertz and SNOM with app.speqqle

Experiments

Do you do optical spectroscopy experiments?

With app.speqqle you can analyse data from almost every optical spectroscopy technique including:

Far field spectroscopy:

Reflectivity
Transmission
Absorbance
Ellipsometry
THz time-domain (coming soon)

Near field spectroscopy:

Bulk Point Dipole model

Bulk Finite Dipole model

Multilayer Finite Dipole model (coming soon)

anlysis and fitting of optical spectra and peaks with app.speqqle

Fitting

Are you looking for an easy way to fit optical spectroscopy data?

With app.speqqle, your data is fitted automatically once you select your experiment. No coding required — it’s literally just one click.

analysis with app.speqqle gives you dielectric constant, refractive index, loss function, optical penetration depth, conductivity, layer thickness and temperature for Raman

Outputs

Do you need to get a specific information from your spectroscopy experiment?

Optical spectra contain a treasure of information and with app.speqqle you can choose which outputs you are interested in:

Dielectric constant
Refractive index
Loss function
Optical penetration depth
Optical spectral weight
Conductivity
Layer thickness (for multilayer samples)
Temperature (for Raman spectroscopy)

Fitting using Drude Lorentz, Tauc Lorentz, Fano, Cauchy lineshapes

Lineshapes

Are you a more experienced user and want to choose the line shapes of your fit?

At the moment app.speqqle lets you select between the following line shapes:

Drude-Lorentz
Tauc-Lorentz
Fano
Cauchy
Sellmeier and many more …

Simultaneous fitting of optical spectroscopy data

Multianalysis

Do you want to analyse more than one spectroscopy experiment at the same time?

A special feature of app.speqqle is the multianalysis of more than one experiment at the same time. If you have, for example, data from an ellipsometry and a transmission experiment on the same sample, you can fit both at the same time to increase the precision of your result.)

batch fitting and analysis of optical spectroscopy data

Batch

Do you want to analyse not only one spectrum but an entire data set?

With the batch functionality of app.speqqle you can repeat the analysis defined for one spectrum for other spectra as many times as needed.
