TLDR
In this paper, the authors reported that at least one positive ion was found to have a knoop hardness of 16 to 18 by means of RADIATION DAMAGE on the surface of a pure aluminum film.Abstract:
ON IMPLATATION OF POSITIVE IONS WITH THE CONCENTRATION OF ABOUT 10**14-10**16 /CM.2 COMPRISED OF AT LEAST ONE OF THE POSITIVE IONS B+, NE+. N+, P+, O+ OR AR+ INTO A PURE ALUMINUM FILM HAVING A KNOOP HARDNESS OF ABOUT 12, UNDER THE IMPLATATION ENERGY ON ORDER OF 45 KEY., THE SURFACE LAYER EXISTING IN THE DEPTH OF SEVERAL THOUSANDS A. FROM THE TREATED SURFACE OF THE ALUMINUM FILM EXHIBITS A KNOOP HARDNESS OF HK=16 TO 18 BY MEANS OF RADIATION DAMAGE. FURTHER, ON APPLYING HEAT TREATMENT WITH TEMPERATURES OF ABOUT 50 TO ABOUT 450*C. TO THE ABOVEMENTIONED INO-IMPLANTED PART, THE SURFACE HARDNESS OF THIS PART IS INCREASED.read more

Patent
Controlled cleaving process
TL;DR: In this paper, an energy source is directed to a selected region of the donor substrate to initiate a controlled cleaving action of the substrate (10) at the selected depth (20), whereupon the cleaving activity provides an expanding cleave front to free the donor material from a remaining portion of the remaining portion.

Method and apparatus for plasma source ion implantation
TL;DR: Ion implantation into surfaces of three-dimensional targets is achieved by forming an ionized plasma about the target within an enclosing chamber and applying a pulse of high voltage between the target and the conductive walls of the chamber as mentioned in this paper.

Method and structure for fabricating solar cells using a layer transfer process
TL;DR: In this paper, an optical coupling material is provided between the first surface region of the thickness of the material and the second surface of the optically transparent material, where the surface region is overlying the first one.

Controlled cleavage process using pressurized fluid
TL;DR: In this article, a technique for forming a film of material (12) from a donor substrate (10) is described. But the technique has a step of introducing energetic particles (22) in a selected manner through a surface of the donor substrate to a selected depth (20) underneath the surface, where the particles have a relatively high concentration.
