H2CO ice rate 0.325 nm.s-1 thickness 316 nm (Layer #1) | SCOOP | SSHADE

Layer

Name: Layer #1

Physical characteristics

Type of layer: compact
Thickness: 316.0 $\pm$ 14.0 $nm$
Texture: compact poor grained
Type of porosity: unknown
Comments: For the thickness measurement of H2CO, we have used a value of 1.33 for the refractive index at visible wavelengths. This value is the one of the liquid phase. Thus a systemetic error on the thickness could exist.

Formation conditions

Formation mode: single gas deposition
Temperature: 25.0 $\pm$ 5.0 $K$
Pressure: 1e-08 $\pm$ 1e-08 $None$
Rate: 0.325 \pm 0.01 $nm.s^{-1}$
Comments: Thin film deposited under vacuum from slow molecular flow of H2CO gas with 1 deposition tube at 45° incidence with the CsI substrate
