A solar cell researcher requested the following quote:

Can you give me quotes on 1 InGaAs wafer as I will be doing experimental work on it for thermophotovoltaic related experiments? I would need very basic cell that does not cost too much as the solar cell will be used in a thermophotovoltaic structure to output electric power with a seperate structure called absorber-emitter layer to change the incoming heat source to NIR region.

InGaAs Substrates for Temperature-Dependent Photoluminescence Measurements

A senior applications scientist requested a quote for the following:

I am looking for some small III-V material wafer pieces (on the order of 1cm2 or slightly smaller) with bandgap approximately 0.8eV.

I need the materials for doing temperature-dependent Photoluminescence measurements (room temp down to 10K), to measure the bandgap shifts. I
want to study 2-3 materials with slightly different but known composition.

InGaAs (standard and strained) is one suggestion, but am open to other ideas.

Broken pieces or scrap materials are fine, as long as the composition is known.

InGaAs to Design Optical Waveguide

A Ph.D candidate requested the following quote:

We are looking for InP/InGaAsP wafers (lattice matched). Attached is the
design layout we have in mind. Our purpose here is to design optical
waveguide where the light is confined mostly in the core region (InGaAsP)
sandwiched by the InP cladding layers:

About the wafers:

  • Wafer #1 for passive application (no free carriers)
  • Wafer #2 option (1) for active application using InP (p+) cap layer
  • Wafer #2 option (2) for active application using InGaAs (p+) cap layer

Question on wafer #2 design:

Which one is better for active application? wafer 2 option (1) or option
(2)?

The one with InGaAs (p+) cap layer has better ohmic contact due less
resistance. However, the InGaAs cap layer is absorptive at 1.55um if
designed under lattice matched condition (please confirm). This is partly
the reason why I increased the upper cladding thickness to 450nm and reduce
the InGaAs layer thickness to 50nm in wafer (2). This is done so that the
light in the core can be isolated better from the cap layer.

Please kindly advice.

Lastly, please also advice on the pricing for:

  • 2 piece of wafer #1
  • 1 piece of wafer #2
