Journal ArticleDOI
Role of vacancy sites and UV-ozone treatment on few layered MoS2 nanoflakes for toxic gas detection
TL;DR: The use of liquid exfoliated MoS2 nanoflakes as the sensing layer in a handheld, resistive toxic gas sensor to detect toxic gases like ammonia and NO holds promises to developing cost-effective, reliable and highly sensitiveMoS2 based ammonia sensors.
Journal ArticleDOI
Fabrication of Si/ZnS Radial Nanowire Heterojunction Arrays for White Light Emitting Devices on Si Substrates
TL;DR: The observed white light emission from the Si/ZnS nanowire heterojunction could open up the new possibility to integrate Si-based optical sources on a large scale.
Journal ArticleDOI
Broadband photoresponse and rectification of novel graphene oxide/n-Si heterojunctions
TL;DR: The transient photocurrent measurements indicate that the GO based heterojunction diodes can be useful for UV and broadband photodetectors, compatible with silicon device technology.
Journal ArticleDOI
A deep submicron Si/sub 1-x/Ge/sub x//Si vertical PMOSFET fabricated by Ge ion implantation
TL;DR: In this paper, a deep submicron vertical PMOS transistor using strained Si/sub 1-x/Ge/sub x/ channel formed by Ge ion implantation and solid phase epitaxy was reported.
