Gallium phosphide (GaP), a phosphide of gallium, is a compound semiconductor material with an indirect band gap of 2.24 eV at room temperature. Impure polycrystalline material has the appearance of pale orange or grayish pieces. Undoped single crystals are orange, but strongly doped wafers appear darker due to free-carrier absorption. It is odorless and insoluble in water.
GaP has a microhardness of 9450 N/mm2, a Debye temperature of 446 K (173 °C), and a thermal expansion coefficient of 5.3 ×10−6 K−1 at room temperature. Sulfur, silicon or tellurium are used as dopants to produce n-type semiconductors. Zinc is used as a dopant for the p-type semiconductor.
Gallium phosphide has applications in optical systems. Its static dielectric constant is 11.1 at room temperature. Its refractive index varies between ~3.2 and 5.0 across the visible range, which is higher than in most other semiconducting materials. In its transparent range, its index is higher than almost any other transparent material, including gemstones such as diamond, or non-oxide lenses such as zinc sulfide.
HI, we are redoing our bathroom and looking for a second opinion.
We are having an issue with the bathtub fitting snugly to the wall, as our wall seems to not be a 90 degree angle. There is 2cm gap at one side as shown on the picture with red line.
What are the options to cover the gap?
Hi I’ve tiled my bathroom floor on top of hardie cement board. I have left expansion gaps all around the wall when I layed cement board. When I grout my floor tiles the grout is going to pour down all the edges into expansion gaps. Is this ok as the grout is flexible? Any help would be...
Hi all, just tiled one of two sides of my shower tray but I’ve left a 7mm gap at the base. Technically and mechanically is this too big? I’d rather not try and redo the bottom row of tiles 🙄
Behind, the plasterboard primed, then silicone sealed then tanking tape then tanking paint before...
Looking for some advice of tiled my en suite and coming towards the end and gap down the edge is getting bigger as I go higher and looks as though will be about a 20mm gap
What do I do?
Hi,
I have an issue here. My tiler has left a gap between the trim and the wall. No doubt the wall wasn’t true.
I have put some pics of this, but it’s hard to show well. The gap can be up to 6mm in places.
Two questions:
1 is this common practice? I would have thought that walls were...
Hello and thanks for your time.
When the shower metal frame (that will hold the glass wall) is placed plumb along the tiled wall, you can see that the tiled wall is uneven. The top and bottom touches the tile wall but in the middle there is a huge 2cm gap between the metal and wall. Basically...
Hello everyone.
My building had bricking work done on the outside and it seems in the process they've yanked the shower window away from where it was seated before. Creating this gap between the tile and exterior frame. How do I fill this gap? Should I use grout or something else? Thank you!
When laying 1st row of porcelain tiles following line of house wall, Is it best I leave a gap for grout or but up direct against house wall? Thanks regards The Famous Forry.
Hi
I am trying to correct some work performed by my tiler. I have sent photos to him of the things I’m not happy with but he can’t see the issue.
The trims are cut awfully? Can we cover these in any way?
There is a gap about an inch above the shower wall tiles where he said he couldn’t get a...
WHOLE BATHROOM REFIT - ALL WALL FULL HEIGHT TILING AND TILED WINDOW LEDGES. ONE SMALL WINDOW & ONE LARGE WINDOW DIRECTLY OPPOSITE BATHROOM DOOR. PREVIOUS SILL HEIGHT & TILES WERE RIGHT UP TO WOODEN WINDOW FRAME (SEE LAST PHOTO WITH CLOCK)).
NEW TILES PLACED SO THAT WINDOW LEDGE HEIGHT WAS NOT...
So, I've tiled most of the wall in my downstairs WC and am left with a narrow floor to ceiling strip at each end of about 25mm (see pic)
The majority of this gap will have the flat section of the tile trim so what should I use to stick the tile strips with?
I'm assuming the standard tile...
Hi, please looking for some advice, so we had a horrible tiler leave a tiny gap between the tiles and the ceiling, I honestly don't know what to cover it with to make it look seamless. The tiler lied to us and later we found out he's never actually tiled before. Any advice will be appreciated.
Hello, we’ve just had a bathroom tiled. A 1.5cm gap is at the top, between the tiles and ceiling, which has been grouted. I wondered if this was normal? I think it looks slightly odd and worry that such thick grout will crack and look bad over time. I wondered if there was any way of fixing it...
Hi all
I have to replace a handful of quarry tiles on a cement based kitchen floor. I guess a long time ago these tiles were laid directly onto cement (with the cement potentially as the adhesive).
I now have thinner tiles so I can relay them onto the concrete only the space between the tile...
Ok so ive messed up a bit when tiling my shower room - after spending ages measuring tiles and where to start to avoid small cuts and getting the boarder in the right place, i placed a baton and tiled off that ive now tiled down to my shower tray and i am out by about 5mm - so rather than...
Hi,
I have just tiled my bathroom wall and done the last row around the shower tray. I wasn’t sure how much gap to leave but it ranges between 4mm and 5mm.
I have tanked the walls and used the Mapei tape also around the shower tray.
Are those size gaps ok? Looks like sealant would fill them...
Hi,
Had a walk in shower fitted which is currently being tiled. Noticed that the tradesmen are tiling over a corner gap between 2 wallboards without filling it in first. Is this normal practice?
Photo attached, the gap is approx 0.5 cm
Hi all,
I live in Cyprus. Bought a new build top floor flat a couple of years ago with a roof garden. Have had a whole host of things that needed sorted out including having to re-grout the exposed roof garden/top floor balcony due to the grout crumbling for some reason and water getting under...
Hi all! Might be an easy question for the pros!
I have a 12x14 tile that I am going to vertically stack to the ceiling. Not too fancy. However from the top of the tub to the ceiling is about 76" which would be 3 tiles (about 72" with a little for the 1/16" grout) That would leave about a 3.5"...
Hi,
We are currently getting our en-suite tiled and there seems to be an issue.
On one of the walls where the tiles are exposed, there is no gap at the very top but as you work your way to the bottom there is about a 10mm gap.
The tiler said that the wall surface wasn't flat but the wall is...
